What is the cotyledon?

The cotyledon stores food for the seed and are the first leaves of the baby plants.

What are members of the Plant Kingdom described as?

Autotrophs

What are protoctists?

They are microscopic single- celled organisms.

What do Euglena possess?

They possess chloroplasts and make their food through photosynthesis

What are Amoeba?

Amoeba digest solid food and are described as animals.

How are fungi produced?

They are produced by spores.

What are Fungi made up?

Fungi are made up of thread like hyphae.

What are dichotomous keys used for?

They are used to divide the organisms in the key into smaller and smaller groups.

What are ribosomes and what do they do?

They make protein

What Is the Mitochondria?1

It is the powerhouse of the cell- respiration occurs here to release energy

What is the cytoplasm?

It is a jelly like substance that fills the cell and where most chemical reactions happen

What is the nucleus?

Controls the chemical reactions in the cell.

What is the cell membrane?

Controls the movement of substances in and out of the cell

What is the cell wall?

Helps keep the cell rigid

What is the vacuole?

Supports the cell and contains cell sap

What are the chloroplasts?

Contains the pigment chlorophyll.

what do red blood cells do?

Transports oxygen from the lungs to the tissues. Has hemoglobin to bind with oxygen

What do muscle cell do?

Contracts so that the structures can be brought closer together

What do ciliated cell do?

Has a layer of tiny hairs which can move and push mucus. The mucus transported trapped dust and microbes.

What do motor nerve cells do?

They conduct nerve impulses. They have a long fiber called axon which impulses a fatty sheath which gives electrical insulation.

what do Root hair cells do?

They absorb water and minerals from the soil.Has long extension which increases the surface area for absorption.

What does the xylem cell do?

It transports water and supports the plant.

What is endoplasmic reticulum?

Studded with ribosomes and is involved in producing and transporting proteins.

What is the mitochondria?

Powerhouse of the cell. Provides energy in the form of ATP by carrying out aerobic respiration.

What is the equation for respiration?

Glucose+ oxygen= carbon dioxide+water+ energy

Which cells do not have mitochondria?

prokaryotes

What is the binomial name for a modern day human?

Homo Sapiens

How do we classify organisms?

Using morphology, anatomy and DNA
