Read the question and carefully look at the images. Make a habit to look at the image because 90% of the time the answer lies in the images

• True

• False

• Neither

Match the following

• Stem moves food produced in the leaves down to the roots in tiny tubes.

• Stem/Phloem

• Absorb water and minerals and move them up to the stem

• Roots/Xylem

• The part of the plant that is generally under the ground and in the soil.

• Root

Match the image to the correct TROPISM

• Hydrotropism

• 
• Thigmotropism

• 
• Phototropism

• 
• Thermotropism

• 
• Gravititropism

• 

Answer explanation

The growing or developing movements made through plants in response to contact with a solid object are called thigmotropism.

The meaning of SELF-POLLINATION is the transfer of pollen from the anther of a flower to the stigma of the same flower

• True

• False

• Neither

Answer explanation

Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary, where the sperm fertilizes the egg.

A flower that has both male and female reproductive structures is shown.

Which statement best describes an interaction that will allow a flowering plant to reproduce by self-pollination?

• An anther is transferred from a filament to another filament within the same flower.

• An ovule is transferred from the ovary to a petal on a different flower.

• A pollen grain is transferred from an anther to the stigma of the same flower.

• An ovary is transferred from a flower on one plant to a flower on a different plant.

Answer explanation

The meaning of SELF-POLLINATION is the transfer of pollen from the anther of a flower to the stigma of the same flower

Plants get their micro nutrients that can be added to soil. The fertilizers that help plants grow or make grass look greener are usually absorbed through roots of the plants.

The fertilizers and chemical is absorbed by plant ROOTS from soil and then -

• Transported to reproductive tissues by the plant’s shoot system

• Stored in plant stems until the flowers are pollinated

• Concentrated in the roots until the plant’s reproductive tissues mature

• Transported by the phloem to the stomata in leaves, where it attracts pollinators

Answer explanation

The plants absorb water and nutrients, fertilizers and transport them through the roots to the shoots and other parts of the plant.
