Intracellular digestion occurs through the action of lysosomes. Cell structure and function review answer key. The trillions of cells in your body make your way of life possible. In 1665, Robert Hooke, an English scientist, published his book Micrographia, in which he described that pieces of cork viewed under a microscope presented small cavities, similar to pores and filled with air. In photosynthesis, solar energy is transformed into chemical energy, the energy of the chemical bonds of the produced glucose molecules (and of the molecular oxygen released).

Cell Structure Review Answer Key West

In larger organisms, the main purpose of a cell is to organize. Cells have problems functioning when they get too big. This hypothesis is strengthened by some molecular evidence, such as the fact that mitochondria have their own independent DNA and protein synthesis machinery, as well as their own RNA and ribosomes, and that they can self-replicate. The membrane that encloses vacuoles is called the tonoplast, named after the osmotic function of the structure. Are any bacteria made of more than one cell? Chloroplasts are the key structure in the process of photosynthesis. What substances make up the nucleolus? You might see hydra, amoebas, or euglena. The main concept of cell theory is that cells are the basic structural unit for all organisms.

Cell Structure Answer Key Pdf

One Name, Many Types. Autophagic digestion occurs when residual substances of the cellular metabolism are digested. The nucleolus is a region within the nucleus made of ribosomal RNA (rRNA) and proteins. Because they have their own DNA, RNA and ribosomes, mitochondria can self-replicate. For example, the interaction between actin-containing filaments and the protein myosin creates pseudopods. What is the basic morphology of these organelles and in which cells can they be found? What substance are plant cell walls made of? What is the difference between the smooth and rough endoplasmic reticulum?

Cell Structure Questions And Answers Pdf

They might group together to form the tissues of the stomach and eventually the entire digestive system. A protein is an example of a macromolecule while a mitochondrion is an example of an organelle. It is not enclosed by a membrane. Fat droplets and glycogen granules are examples of cytoplasmic inclusions. Which type of cell evolved first, the eukaryotic cell or the prokaryotic cell? Cytoplasmic inclusions are foreign molecules added to the cytoplasm, such as pigments, organic polymers and crystals. They do not have membranes, cell organelles, or own metabolism. What is the plasma membrane of the cell? Viruses are considered the only living organisms that do not have cells. A) With no electric field, the forces acting on the oil droplet were the gravitational force, the buoyant force, and viscous drag.

It is presumed that mitochondria were primitive aerobic prokaryotes that were engaged in mutualism with primitive anaerobic eukaryotes, receiving protection from these organisms and providing them with energy in return. Chromatin, dispersed in the nucleus, is a set of filamentous DNA molecules attached to nuclear proteins called histones. Based on knowledge discovered later on, what do you think those cavities were composed of? Plant cells are easier to identify because they have a protective structure called a cell wall made of cellulose. Chlorophyll molecules are responsible for the absorption of light energy during photosynthesis. The plasma membrane, also called the cell membrane, is the outer membrane common to all living cells, made of a phospholipid bilayer, embedded proteins and some bound carbohydrates. Lysosomes enfold the substances to be broken down, forming digestive vacuoles or residual vacuoles, which later migrate toward the plasma membrane, fusing with it and releasing (exocytosis) the digested material to the exterior. Sets found in the same folder. The plasma membrane is the outer membrane of a cell, it encloses the cell itself, maintaining specific conditions for cellular function within the cell.

Cell Structure And Function Review Answer Key

Eukaryotic cells can be divided into three main parts: the cell membrane that physically separates the intracellular space from the outer space by enclosing the cell; the cytoplasm, the interior portion filled with cytosol (the aqueous fluid inside the cell); and the nucleus, the membrane-enclosed internal region that contains genetic material. Plants also have organelles such as the green chloroplast or large, water-filled vacuoles. The aqueous fluid that fills the nuclear region is called karyolymph, or the nucleoplasm. Lysosomes contain digestive enzymes (hydrolases) that are produced in the rough endoplasmic reticulum and stored in the Golgi apparatus. What colors (of the electromagnetic spectrum) are absorbed by plants?

This hypothesis is called the endosymbiotic hypothesis of the origin of mitochondria. Lysosomes and Peroxysomes. The endoplasmic reticulum is a delicate membrane structure that is contiguous to the nuclear membrane and which is present in the cytoplasm. What are the main structures within the nucleus of a cell? Where is that molecule located in photosynthetic cells? Mitochondria are numerous in eukaryotic cells and they are even more abundant in cells that use more energy, such as muscle cells.

Like mitochondria, chloroplasts have two boundary membranes and many internal membranous sacs. By dividing responsibilities among different groups of cells, it is easier for an organism to survive and grow. He measured the terminal speed of a drop when there was no electric field and then the electric field E that kept the drop motionless between parallel, oppositely charged plates. Each DNA filament is a double helix of DNA and therefore a chromosome.

What is the chemical content of those organelles? What are the main structures of the cytoplasm present in animal cells? What are their functions? What are the main respective components of cell walls in bacteria, protists, fungi and plants?

It is made of microtubules, microfilaments and intermediate filaments. Intermediate filaments are also made of protein. Centrioles also produce the aster microtubules that are very important for cell division. What is the fluid that fills the nucleus called? Regarding the presence of the nucleus, what is the difference between animal and bacterial cells? In bacteria, genetic material is contained in the cytosol and there is no internal membrane that encloses a nucleus. Mitochondria are organelles enclosed by two lipid membranes. It is assumed that these organelles were primitive photosynthetic prokaryotes because they have their own DNA, RNA and ribosomes, and can also self-replicate.
