Cell Structure & Function

What is the cytoplasm?

• material that fills the empty space of the vacuoles

• material that fills the empty space of the chloroplasts

• contains DNA

• material that fills the empty space of a cell

What are prokaryotic cells?

• bacterial cells

• plant cells

• cells that do not have membrane-bound organelles

• animal cells

What is the function of chloroplasts?

• stores proteins needed for the cell

• uses energy from the sun to make food

• uses proteins to make food for the cell

What is the function of the mitochondria?

• uses energy from the sun to make food

• makes energy available to the cell

• makes proteins

• removes waste out of the cell

What is the function of the golgi apparatus?

• modifies, packages, and transports proteins and prepares them for use

• uses energy from the sun to make food for the cell

• tightly packs DNA into chromosomes inside the nucleus

What is the function of the cell membrane (plasma membrane)?

• thick, rigid layer providing the cell its structure

• breaks things down

• semi-permeable membrane that regulates what comes in and out of the cell. Surrounds the cytoplasm

What is the function of ribosomes?

• breaks things down

• produces proteins

• transports items around the cell

• produces food for the cell using energy from the sun

What is the function of lysosomes?

• transports materials around the cell

• Uses chemicals to break down food and worn out cell parts

• produces proteins for the cell (protein synthesis)

• storage unit for the cell

What is chlorophyll?

• green pigment in plants that absorb light energy used to carry out photosynthesis

• uses energy from the sun to make food for the cell

• storage unit of the cell

• produces proteins for the cell and helps to transport them around the cell

What is an organelle?

• Organelles are eukaryotic and prokaryotic cells

• nucleus, ribosomes, chloroplasts, vacuoles, ER

• golgi apparatus, lysosomes

• tiny cell structure that carries about a specific function within the cell
