Cell Basics
What is the basic unit of life?
The cell
Which organelle controls the activities of the cell?
Nucleus
Organelle that controls what enters and leaves the cell.
Cell Membrane
Name one structure found in plant cells but not animal cells.
Cell wall or chloroplasts
What would happen to a cell if it did not have a cell membrane
The cell would have difficulty controlling what enters and leaves, which could cause the cell to lose homeostasis.
What is the difference between unicellular and multicellular organisms?
Unicellular organisms have one cell; multicellular organisms have many cells.
Which organelle is known as the powerhouse of the cell?
Mitochondria
Which organelle helps make proteins?
Ribosomes
Which type of cell has a cell wall?
Plant Cell
Why does a cell need energy?
Cells need energy to carry out life processes and cellular respiration.
What do all cells have in common?
All cells have a cell membrane, cytoplasm, DNA/genetic material, and ribosomes.
What organelle is a storage bin where, food, nutrients, and waste are kept?
Vacuole
How does the cell membrane help maintain homeostasis?
It regulates what substances enter and leave the cell, helping maintain stable conditions.
What is the function of chloroplasts?
Chloroplasts capture light energy to help plants make food through photosynthesis.
A cell has a nucleus, cell membrane, cytoplasm, and mitochondria but no cell wall or chloroplasts. Is it most likely a plant or animal cell?
Why are cells considered the building blocks of life?
All living organisms are made of cells, and cells are the smallest units that carry out life processes.
Which organelle is responsible for making food in plant cells?
Chloroplasts
What does the nucleus of a cell contain?
DNA
Why are chloroplasts important to plants?
Chloroplasts allow plants to carry out photosynthesis and make glucose/food
A cell's mitochondria stop working. What major cell function would be affected?
The cell would have difficulty producing usable energy, affecting many cellular processes.
What are the two major types of cells?
Prokaryotic and eukaryotic cells
Name the organelle that makes proteins and explain its job
Ribosomes make proteins.
What is the job of the centrioles in a cell?
Helps the cell divide
Explain why a plant cell needs both chloroplasts and mitochondria.
The plant cell needs chloroplasts to make food and mitochondria to release usable energy from food.
A scientist discovers a cell with a cell wall, chloroplasts, a nucleus, and a large central vacuole. What type of cell is it?
Plant Cell
