Plant Cell
What is the last phase of the cell cycle?
Cytokinesis
Living things must use __________ to survive and carry out life processes.
Energy
This organelle controls the cell and contains DNA.
Nucleus
This structure provides rigid support in plant cells.
Cell Wall
What is the first step in Mitosis?
Prophase
What process do bacteria use to reproduce?
Binary Fission
Name TWO characteristics that something must have to be considered alive.
Any 2 of the 7 characteristics.
This structure controls what enters and leaves the cell.
Cell Membrane
Which organelle is usually much larger in plant cells and stores water?
Central Vacuole
During which stage of the cell cycle is DNA copied?
Interphase
What is the name for a visible group of bacteria grown from one original bacterium?
A bacterial colony
Is a virus considered ALIVE or NOT alive?
No - Not made of cells
Ribosomes mainly build ___________.
Proteins
Why can plant cells make their own food but animal cells cannot?
They have chloroplasts - Chloroplasts perform photosynthesis
What are the 3 main reasons that cells divide?
To help organisms grow, heal, and replace damaged cells.
Why can bacteria reproduce so quickly compared to complex cells?
Simple structure - Fewer parts to copy
This characteristic explains how organisms keep internal conditions stable even when the outside changes.
Homeostasis
What are 3 things that the vacuole stores?
Nutrients, water, waste.
Name TWO structures found in plant cells but not animal cells.
Cell Wall & Chloroplasts
