21.1.1Summarize the structure and function of organelles in eukaryotic cells (including the nucleus, plasma membrane, cell wall, mitochondria, vacuoles, chloroplasts, and ribosomes) and ways that these organelles interact with each other to perform the function of the cell.
5NUCLEUS Directs all cell activities Contains instructions for everything the cell doesThese instructions are found on a hereditary material called DNA
6Plasma Membrane Protective layer around ALL cells. Allows things in and out of cells.Helps cell maintain homeostasis (internal balance).
7CELL WALL protects the cell gives shape is made of cellulose A cell wall is found in plants, algae, fungi, & most bacteria.NOT found in animal cells.Located outside the cell membrane.
8MITOCHONDRIAOrganelles that break down glucose to make ATP- process called cellular respiration.AKA the powerhouse.Inner folded membranes= increase in surface area= more energy production during aerobic cellular respiration
9VACUOLES Temporary storage spaces Store food, water, waste Take up most of a plant’s cells volume.
10Chloroplasts Green organelles that make food= photosynthesis found only in plant cells
12RIBOSOMES Site of protein synthesis! = to make proteins Float freely or attached to the endoplasmic reticulum (ER)In ALL cells!
13The Cell is like a Factory DNA from the nucleus codes for proteins.Proteins are used as enzymes for chemical reactions:Energy production at the mitochondriaMaking glucose in the chloroplastDigesting large organic molecules
14Life’s Levels of Hierarchy Atoms-> Molecules-> Organelles-> Cells >Tissues -> Organs -> Organ Systems -> OrganismsThis applies only for multicellular organisms.
