What the Cell?(Cell parts)
This part of the cell contains DNA and controls the cell's activities.
What is the nucleus ?
This cell part is found in plant cells but not animal cells, and gives the cell a fixed shape.
What is the cell wall?
This characteristic of life releases energy from food, usually using oxygen.
What is respiration?
An organism made of only one cell is described as this.
What is unicellular?
This scientist first used the word "cell" in 1665 after looking at cork.
Who is Robert Hooke?
This thin layer surrounds the cell and controls what enters and leaves.
What is the cell membrane?
This green structure in plant cells carries out photosynthesis.
What are chloroplasts?
An increase in the size or number of cells is this characteristic of life.
What is growth?
Humans, oak trees and celery plants are all described as this.
What is a multi-cellular organism?
This brown stain is used to make plant cells like onion easier to see.
What is iodine?
This cell is red in colour and found in the blood.
Red blood cell.
The cell wall is made of this tough substance.
What is cellulose?
A plant shoot bending towards light is an example of this characteristic.
What is sensitivity (responding to stimuli)?
Name one unicellular organism you might see under a microscope.
What is: amoeba, yeast, Paramecium, Euglena or bacteria?
The microscope is needed to see cells because most are too small to be seen with this.
The microscope is needed to see cells because most are too small to be seen with this.
These structures are the site of respiration, releasing energy for the cell.
What are mitochondria?
This large sac in plant cells stores cell sap and helps keep the cell firm.
What is the vacuole?
Removing waste products such as carbon dioxide and urea from the body is called this.
What is excretion?
A red cell found in the blood that has no nucleus
What is a red blood cell?
This is the name for the building blocks that all living things are made of.
What are cells?
Cells that need lots of energy, like muscle cells, have a large number of these
What are mitochondria?
Explain why root cells, unlike leaf cells, do not contain chloroplasts.
What is: roots are underground, so there is no light for photosynthesis?
A car moves, uses fuel and gives off waste gases, but it is not alive. Name one characteristic of life it does not show.
What is: growth, reproduction or sensitivity?
Put these in order from smallest to largest: organ, cell, organism, tissue.
What is: cell, tissue, organ, organism?
Give one reason why a stain is added to a slide.
What is: to make the parts of the cell show up more clearly?
