What are the three features of an animal cell?
|
Cell membrane, cytoplasm and nucleus.
|
|
|
What are the features of a plant cell?
|
Cell membrane, cytoplasm, chloroplasts, nucleus, cell wall and a vacuole.
|
|
|
Single celled organisms are called...
|
Unicellular.
|
|
|
Many celled organisms are called...
|
Multicellular.
|
|
|
All living things are made up of...
|
Cells.
|
|
|
What is an organelle?
|
A membrane bound organism thatr performs a specific function.
|
|
|
What is the function of chloroplasts?
|
The chloroplasts carry out photosynthesis and contain chlorophyll to trap the light energy.
|
|
|
Chloroplasts are not found in animal cells. List two other properties that animal cells don't have.
|
Cell wall and a permanent vacuole.
|
|
|
Give the deffinition for both properties you have listed that are not found in animal cells.
|
Cell wall- covers the cell membrane and helps to support the cell.
Vacuole- permanant pool of sap. |
|
|
Most organells are found in the cytoplasm. The cytoplasm is inside the cell wall. What is the function of the cytoplasm?
|
The cytoplasm helps keep the cell alive. Chemical reations go on inside the cytoplasm.
|
|
|
DNA is a long line of genes curled up. Genes contains all the characteristics of the cell. Where are the genes found?
|
In the nucleus.
|
|
|
What is a specialised cell? List the deffenition.
|
Cells that adapt to allow them to perform specific functions.
|
|
|
Red blood cells are specialised cells. What do they do? what do they carry? and what is special about their shape? (3)
|
Red blood cells carry oxygen around the body(1). They contain a substance called haemoglodin (1). They have a bi-concave shape to allow oxygen to pass in and out more easily. (1)
|
|
|
Root hair cells are found where? What are their special features? (2)
|
Cells found in roots of plants (1). They are long and thin to allow them to absorb water and minerals from the soil (1).
|
|
|
What are the special features about leaf palisade cells. What do they contain and what do they carry out? (2)
|
Leaf palisade cells carry out photosynthesis to provide the plant with energy (1). They contain lots of chloroplasts (2).
|
|
|
Xylem cells are found where? What is their function? (2)
|
Xylem cells are found in the stems of plants (1). They help carry water up the stem through little tubes (2).
|
|
|
What type of cell is an amoeba?
|
Unicellular.
|
|
|
Where do amoebas live? (1)
|
In damp places such as ponds and ditches. (1)
|
|
|
Spirogyra has many cells, we call this... (1)
|
Multicellular. (1)
|
|
|
Wha is a prokaryotic cell? (1)
|
There are no membrane bound organisms found inside the cell. (1)
|
|
|
A bacterium is a prokaryotic cell. Which one of these features does a bacterium cell have. Plasmids, chloroplasts, food storage, nucleus, mitochondria, cell wall, ribosomes and a cell membrane. (5)
|
Plasmids, food storage, cell wall, ribosomes and a cell membrane. (5)
|
|
|
In bacterium where are the genes found? (1)
|
Not in a distinct nucleus. (1)
|
|
|
What is a eukaryotic organism? (1)
|
Where there are membrane bound organells. (1)
|
|
|
Give three examples of eukaryotic organisms. (1)
|
Funghi or animals, plants or yeast.
|
|
|
Out of these cells which of these are eukaryotic? (3)
|
Amoeba (1), cheek cell (1), bacterium and root hair cell (1).
|
|
|
Yeast is a eukaryotic cell. Which four of theese does a yeast cell have? Nucleus, chloroplasts, vacuole, cytoplasm, ribosomes, cell wall and cell membrane. (4)
|
Nuclues, cytoplasm, cell wall and cell membrane. (4)
|
|
|
Organells have adaptations one of these is that root hair cells have no chloroplasts.Why don't root hair cells have chloroplasts? (1)
|
They don't see the light. (1)
