Plants take in water through
- root hair cells
- roots
- xylem cells
- palisade cells
Where would you find palisade cells?
- in a leaf, near the top surface
- in a root
- in your lungs
- in your blood
Stomata are
- holes in the underside of a leaf, to allow gases in and out
- a red fruit
- a skin disorder
- puncture marks on your skin after an injection
Microscopes have
- an eyepiece lens and an objective lens
- an eye lens and an object lens
- an eyepiece lens and a magnifier lens
- a focus lens and an eyepiece lens
We stain a microscope slide
- so that we can see parts of cells more clearly
- so that the colours are more realistic
- so that the cells do not decay
- so that the cells stick to the slide
Animal cells don't have
- a cell wall
- a nucleus
- a cell membrane
- cytoplasm
Nerve cells
- carry messages
- have long tails so they can swim
- carry water in plants
- carry oxygen
red blood cells
- carry oxygen
- have tails so they can swim
- fight off invaders in our bodies
- carry messages
white blood cells
- fight off invaders in our bodies
- carry oxygen
- have tails so they can swim
- carry messages
sperm cells
- carry genetic information
- do not carry genetic information
- do not have tails
- carry oxygen
The stomach
- adds acid to the food to break it down
- pumps blood around the body
- produces bile
- absorbs water from the food
The oesophagus
- connects the mouth to the stomach
- adds acid to food to break it down
- connects the stomach to the small intestine
- digests fats
Digestive system: which is the correct sequence?
- mouth, oesophagus, stomach, duodenum, ileum, colon
- mouth, stomach, duodenum, oesophagus, ileum, colon
- mouth, duodenum, stomach, oesophagus, ileum, colon
- mouth, ileum, stomach, oesophagus, colon, duodenum
Digestive system: which is the correct sequence?
- mouth, gullet, stomach, intestines
- mouth, stomach, gullet, intestines
- mouth, intestines, gullet, stomach
- mouth, gullet, intestines, stomach
The oesophagus is also known as the
- gullet
- windpipe
- intestine
- artery
The lungs
- allow oxygen from the air into our bloodstream
- add acid to the food to break it down
- absorb water from the food
- have a small surface area
The gullet
- connects the mouth to the stomach
- adds acid to food to break it down
- connects the stomach to the small intestine
- digests fats
The kidneys
- filter the blood to remove waste
- pass oxygen into the blood
- remove carbon dioxide from the blood
- pass nutrients into the blood
cytoplasm
- is where most chemical reactions happen in a cell
- hold the cell rigid
- carries genetic information
- allows nutrients to pass into the cell
Insects visit flowers because
- they feed on the nectar
- they feed on the pollen
- they are attracted by the pollen
- they can shelter from rough weather
The male part of a flower, that produces pollen, is called the
- anther
- filament
- stamen
- style
The female part of a flower, where pollen is deposited, is called the
- stigma
- style
- ovule
- carpel
Xylem is
- a system of long plant cells that carry water around the plant
- a substance found in the nucleus of cells
- a glue used when preparing microscope slides
- a system of long plant cells that carry food around the plant
In a plant cell, photosynthesis occurs in
- Chlorophyll, a green substance in the chloroplasts
- Chloroplasts, a green substance in the chlorophyll
- the cell wall
- the vacuole
The watery substance in cells is called
- cytoplasm
- xylem
- vacuole
- mitochondria
We can see very small objects using a
- microscope
- telescope
- microtome
- microfiche
the thing we're looking at with a microscope is called the
- specimen
- objective
- stage
- focus
the microscope lens that is closest to the slide is called the
- objective lens
- eyepiece lens
- concave lens
- collimator
a picture taken using a microscope is called a
- photomicrograph
- photograph
- micrograph
- telegraph
Chloroplasts
- contain chlorophyll
- contain DNA
- control the cell
- are part of the cell wall
