cells Flashcards
What are the similarities in plant and animal cells
Nucleus, cytoplasm and cell membrane
What are the differences in plant and animal cells
plant cells also have cell wall, vacuole and chloroplasts
What is the role of a nucleus
controls the activities of the cell
What happens in the cytoplasm
where the chemical reactions take place
What is the role of the cell membrane
controls what goes in and out of the cell
What does a cell wall do
strengthens the cell
What is inside the vacuole
it is filled with cell sap
What do chloroplasts do
absorb light energy to make food
What are the mitochondrion used for
aerobic respiration
What are the different parts of a microscope
eye piece objective lens stage course focus light source fine adjustment focus
How do you work our magnification
size of image / actual size
What are the four types of cells
Animal, plant, fungus(yeast) and bacteria
Which two cells are multi cellular
animal and plant
which two cells are unicellular
fungus(yeast) and bacteria
Name the specialized cells
Guard cells, sperm cell, red blood cell, egg cell, root hair cell, white blood cell and a nerve cell(neuron)
What do guard cells do
they change shape and open and close to form the stomta
How are egg cells adapted
they have a large food store
how are neurons adapted
they are long so they can make connection around the body
they have dendrites to allow nerves to make connections
contain myelin sheaths to insulate
How are root hair cells adapted
have a high surface area to absorb more water and mineral ions
How are sperm cells adapted
has an acrosome which contains an enzyme to break down the egg
mitochondria to power the tail
tail to help it swim
how is a red blood cell adapted
no nucleus to save space so it can be filled with hemoglobin
Biconcaved disc for a large surface area
how is a white blood cell adapted
Has a looped nucleus to change the shape allowing it to engulf bacteria
