Cell organelle essay questions

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.

It is assumed that these organelles were primitive photosynthetic prokaryotes because they have their own DNA, RNA and ribosomes, and can also self-replicate.

Quiz: Cell Organelles and Their Functions

What is the fluid that fills the nucleus called? The walls of the cavities observed by Hooke were the walls of the plant cells that form the tissue.

What substances is chromatin made up of? Cell organelles, such as the Golgi complex, mitochondria, chloroplasts, lysosomes, the endoplasmic reticula and the nucleus, are also enclosed by membranes. Within the nucleus of a cell, the main structures are: The rough endoplasmic reticulum has a large number of ribosomes attached to the external side of its membrane.

Are there living organisms without cells? There is a difference between the optimum color frequency for the two main types of chlorophyll, chlorophyll A and the chlorophyll B. The endosymbiotic theory can also be applied to chloroplasts. In bacteria, genetic material is contained in the cytosol and there is no internal membrane that encloses a nucleus.

Cellular respiration is the process of using an organic molecule mainly glucose and oxygen to produce carbon dioxide and energy. Intracellular digestion occurs through the action of lysosomes. Ribosomes can be found unbound in the cytoplasm, attached to the outer side of the nuclear membrane or attached to the endoplasmic reticulum membrane that encloses the rough endoplasmic reticulum.

What is the observed structure called? It also facilitates the transport of substances across the cell and the movement of cellular organelles.

Animal cells the cells of organisms of the kingdom Animalia have an interior membrane that encloses a cell nucleus and are therefore eukaryotic cells. These cell structures are composed of microtubules that originate from the centrioles. Chlorophyll molecules are responsible for the absorption of light energy during photosynthesis.Learn with flashcards, games, and more — for free.
