This flexible covering protects the inside of a cell and controls what enters and leaves.
cell membrane
Small organelles that make proteins
ribosome
Organelle that powers cells by carrying out chemical reactions.
mitcohondria
This organelle directs cell activities and contains DNA
nucleus
This stiff structure outside the cell membrane supports and protects some cells
cell wall
This organelle stores food, water, and waste materials
vacuole
This usable form of energy is made during cellular respiration.
ATP
This molecule carries instructions for making the proteins a cell needs.
DNA
This word describes a membrane that lets only certain materials pass through.
semipermeable
This organelle gets proteins ready for their jobs and packages them into vesicles.
Golgi apparatus
These plant-cell organelles use light energy to make glucose.
chloroplasts
This organelle in the nucleus makes ribosomes.
nucleolus
Name two kinds of cells that have a cell wall.
plant cells, fungal cells, bacteria, or some protists?
This type of ER has ribosomes attached and is where proteins are produced.
rough ER
What two substances do chloroplasts use with light energy to make glucose?
water and CO2
According to the notes, how does the nucleus control cell activity?
directing protein synthesis (how to make it and how to disperse and use it)
Why can a cell that grows too large have trouble moving materials?
because its volume increases faster than its surface area, leaving too little membrane for moving enough nutrients in and waste out?
What do vesicles and lysosomes do?
vesicles transport substances around the cell, while lysosomes help break down and recycle cell parts
What structures help distinguish a plant cell from an animal cell?
cell wall
chloroplast
uniform, boxy shapes
These cells have cell walls and chloroplasts.
