What does the plant use the glucose for?
Lots of things but mainly for photosynthesis.
To make new molecules like starch, and to release energy in respiration and keep the plant alive.
For making carbon dioxide and water.
For making oxygen.
Where does photosynthesis happen?
inside the cell membrane inside the leaf cells.
Inside the cell wall inside the leaf cells.
Inside the chloroplasts inside the cells (mainly in the leaf cells).
Inside the mitochondria inside the leaf cells.
Plants also need minerals to stay healthy. The minerals are dissolved in the water taken up by the roots. The mineral (a) is needed by the plant to make chlorophyll.
What is pollination?
Pollen from the anther comes into contact with the stigma.
The nucleus from the pollen fuses with the nucleus of the egg cell.
The pollen from the stigma touches the anther.
The pollen from the ovary touches the egg.
In plants, which is these is fertilisation?
The female nucleus of the egg cell fuses with a another female nucleus inside the ovule.
The female nucleus moves up the style and fuses with the pollen nucleus on the stigma.
The male nucleus from the pollen fuses with the female nucleus of the egg cell. This happens inside an ovule.
The pollen grain fuses with the ovule.
Which disease is caused by a bacteria?
measles
cholera
corona virus
chicken pox
Your white blood cells are part of your immune system and are there to destroy dangerous microbes that get into your body. Some white blood cells produce chemicals which destroy microbes like viruses. What are these chemicals called?

enzymes
poisonartis
toxinosus
Luckily with bacterial infections we have a type of medicine which kills most bacteria. What is this called?
antimalarials
antivirals
antibiotics
antibotulisms

alvioluses
spaghetti
ravioli
alveoli

In adult human females, ovulation happens once every 4 weeks (on average). What is ovulation?
When an egg cell or ovum is released from an ovary into the oviduct.
When an ovum fuses with a sperm cell.
When an egg cell or ovum buries itself into the wall of the uterus.
When a sperm cell is released into the oviduct.
