What does the root do
Hold the plant on soil, takes up water and minerals
What does the stem do
Support leaves, transports nutrients
What does the leaf do
Produce food by photosynthesis
What does the flower do
Contains the reproductive organs
What is absorption
Taking up water and minerals from the ground
Nutrient are transported through the…
Xylem tube
What does water evaporate through
The stomata
Lack of water will make the plant…
Wilt
Nitrogen is needed for the____of the plant and an absence causes____
Leaf development, yellow leaves and poor growth
Phosphorus is needed for the____of the plant and lack of it causes____
Root development, poor growth
Potassium is needed for the____of the plant and lack of causes____
Flower and fruit development, yellow leaves and grow abnormally
Define photosynthesis
The process by which plant make biomass and oxygen from water and carbon dioxide using energy in light that has been captured in chorophyll
What are the steps of “the starch test”
1-leaf dipped boiling water soften
2-leaf boiled in ethanol to remove chlorophyll
3- iodine solution over leaf
4- blue/black colour show starch presents
What are the stages of photosynthesis
Water, Carbon dioxide and sunlight enter leaves —> photosynthesis happens using the suns energy captured in the chlorophyll —> glucose is produced along with oxygen —> the glucose is transformed into starch which is then stored
How do u de starch a plant?
You leave it in a dark room for a few days
What is a variegated leaf?
A leaf the has green parts where the chlorophyll is present and white parts where it is not present
Go into your photos and look at the plant diagram
Did you know everything?
What is pollination, and what happens after it?
The transfer of pollen from the anther to the stigma, after a tube grows down from the stigma through the style and into the ovary
What is fertilization?
The male gamete travels down the pollen tube to the gamete in an ovule
When does fertilization occur
When the male gamete and the female gamete fuse
What happens after fertilization?
The ovule forms a seed and the seed and the ovary becomes a fruit
What are some ways a fruit can be dispersed
Wind, animals eating and then pooping out the seeds, the fruit getting stuck in and animals coat
Why does the fruit disperse?
they speed out so there is enough soil, Light and water for the plants
