Plant nutrition
What is plant nutrition?
The process by which the plants obtains the nutrients and energy they need to live.
what are the male parts of the flower?
The stamen, the anther located at the top of the stamen and the pollen produced in the anther.
What are the three ways that a seed is spread?
1. Some animals eat them and later eliminate their seeds in their excrement.
2. Some have long hair attached to the seeds, and the wind carries them.
3. Some have tiny hooks and are carried to other places in animal fur.
What is asexual reproduction?
Some plants do not need seed, they use parts of themselves to reproduce.
Ploughing is the process by which farmers place seeds in the soil.
False, that is sowing.
This part of the plant is where photosynthesis happens.
What are the leaves
What is the female part of the flower?
The pistil, the stigma and the ovary that contains the ovule.
What is germination?
When the seeds fall to the ground and find moist soil and warm temperatures, germination takes place.
What are the different structures of the asexual reproduction?
Stolons, rhizomes, bulbs and tubers.
A plant could survive without roots and a stem.
What is False. A plant needs roots and a stem to get water and nutrients.
This part of a plant can be woody or flexible. Water and food travel up and down this part to get to the leaves and flowers.
The stem
The stamen and the pistil are protected by...
the corolla
What does each seed contain?
An embryo, a miniature plant with a root, a stem and a shoot, and a food store.
Give me one example of stolon, and explain it.
These are specialized stems that grow horizontally above the ground: strawberries.
Fertilizing is the process by which farmers use fertilizers that contain mineral salts.
True.
This part of the plant takes water and nutrients from the soil and sends it to other parts of the plant
The roots
All the petals form the....
corolla
Draw the parts of a seed
drawing
Explain rhizomes and give me one example.
Specialized stems that grow horizontally underground: ginger or irises.
Pruning is the process by which some branches are cut from trees and bushes.
False
What is photosynthesis?
The leaves takes in carbon dioxide from the air through the stomata. Carbon dioxide mixes with raw sap in the leaves, transforming it into elaborated sap. This process is called photosynthesis. Sunlight is trapped by a green substance called chlorophyll found in the leaves. During this process plants release oxygen.
calyx
What are the two types of pollination?
Insect pollination and wind pollination
Give me one example of tuber and explain it.
Underground stems that develop roots, they have stems and roots that emerge from growing points called eyes: potatoes.
Harvesting is the process by which farmers spray plants with pesticides to stop insects harming the crops.
False, this is fumigation.
