Organisation of Cells
This refers to organisms that consist of a single cell
What is unicellular?
Plants use this process to create energy
What is photosynthesis?
These tubes transport water from the roots to the leaves
What are xylem?
Humans breath out more of this gas than they breath in
What is carbon dioxide (CO2)?
These cells transport oxygen around the body
What are erythrocytes (red blood cells)?
This refers to a group of the same type of cell working together
What is a tissue?
Plants use this system to obtain water
What is the root system?
These tubes transport sugars and other nutrients around the plant
What are phloem?
Fish use these structures to obtain oxygen from water
What are gills?
These chambers of the heart pump blood around the body
What are the ventricles?
These cells form linings and surfaces in the body
What are epithelial cells?
This part of a flower produces pollen
What is an anther?
Plants can exchange gases through these structures on leaves
What are stomata?
These two types of digestion both occur in the stomach
What are physical and chemical digestion?
This organ is enlarged in koalas, allowing them to digest the cellulose in leaves
What is the caecum?
These organisms lack internal membranous organelles
What are prokaryotes?
These outer layers of leaves are waxy and protect the inner layers
What are the cuticles?
Evaporation of water from the leaf creates this, causing water to be drawn up the plant
What is negative pressure?
These folded structures in the intestinal wall increase the surface area for absorption
What are villi?
Insects have this sort of circulatory system where haemolymph is pumped into a single body cavity
What is an open circulatory system?
This type of cell consists of a cell body with many root-like appendages and a long thin axon
What is a neuron?
This plant hormone makes grass grow towards the sun
What is auxin?
Phloem sap transports sugars using this process
What is translocation?
All animals need to eat other organisms to obtain nutrients making them this type of organism
What is a heterotroph?
This transport system removes waste from cells
What is the lymphatic system?
