2.2.1 Cell Structure Flashcards
Eukaryotic cells have what type of structures contained within their cytoplasm
Eukaryotic cells have subcellular structures contained within their cytoplasm
Each cellular structure carries out, what?
Each cellular structure carries out a particular function
Organelles are subcellular, “what”?
Organelles are subcellular ‘compartments’ where specific processes take place within the cell
Within the cytoplasm, name organelles that are visible in all cells when looking at a high magnification
Mitochondria
Ribosomes
Vesicles
The main subcellular structures in animal cells are:
The nucleus: contains genetic material
Cell membranes: controls what enters and leaves the cell
Mitochondria: site of aerobic respiration
Ribosomes: site of protein synthesis
Cytoplasm: chemical reactions take place in this jelly-like substance
In addition to the subcellular parts found in animal cells, plant cells have:
A cell wall made of cellulose: gives the cell shape and protection
A permanent vacuole filled with cell sap: pushes the cytoplasm against the cell wall, keeping the cell turgid
Plant cells found in the leaf and stem may also contain chloroplasts: the site of photosynthesis
