What are Plants?
Parts of a Plant – Functions & Diagram:
Plants are organisms that can photosynthesize. This means that they can use the sun’s energy to create their own food. Plants come in a variety of shapes and sizes, and can be found in nearly every environment on Earth.
Plant Ecology
Plant ecology is the scientific study of the distribution and abundance of plants, the effects of environmental factors on plant populations, and the interactions between plants and their environment.
Different Parts of a Plant
- The roots are the part of the plant that anchors it in the soil and absorbs water and nutrients from the soil.
- The stem is the part of the plant that transports water and nutrients from the roots to the leaves and flowers.
- The leaves are the part of the plant that absorbs sunlight and carbon dioxide from the air and uses them to produce food for the plant.
- The flowers are the part of the plant that produces seeds.
Roots
Roots are the underground parts of a plant that anchor it in the soil and absorb water and minerals from the soil. The root system also helps to store food for the plant.
Stems
- are the main supportive structure of a plant. They are the part of the plant that grows out of the ground and into the air. Stems are made of thin, flexible tissues called xylem and phloem. The xylem carries water and minerals from the roots to the rest of the plant, and the phloem carries the food made by the leaves to the rest of the plant.
- The stem of a plant is like the spine of an animal. It is the main support for the plant and helps it to grow tall. The stem is also important for transporting water and food throughout the plant.
Leaves
- Leaves are food factories
- Leaves are food factories because they produce food for the plant. The leaves use sunlight to produce food from carbon dioxide and water. The food is used to help the plant grow and to produce flowers and fruits.
Flowers
- are the reproductive structures of angiosperms, the most common group of plants on Earth. Angiosperms have flowers because the flowers are where the plant’s sex cells are produced. The flowers are also where the seeds are produced.
- Flowers are made up of four parts: the sepals, the petals, the stamen, and the pistil. The sepals are the green parts of the flower that protect the petals and the stamen. The petals are the colorful parts of the flower that attract pollinators. The stamen are the male parts of the flower and the pistil are the female parts of the flower.
Fruits
- Fruits are excellent sources of fiber, vitamins, and minerals, and they are low in calories. Eat a wide variety of fruits every day to get the most benefit.
- Fresh, frozen, canned, and dried fruits all count as part of your fruit intake.
- Fruit juices, smoothies, and fruit drinks also count, but they are not as nutritious as whole fruits.
- Some fruits are higher in sugar and calories than others. So, if you are trying to lose weight, eat those fruits that are lower in sugar and calories.
Examples of fruits that are low in sugar and calories include:
- apples
- bananas
- berries
- cantaloupe
- figs
- grapefruit
- kiwi fruit
- lemons
- oranges
- pears
- pineapple
- watermelon
Examples of fruits that are higher in sugar and calories include:
- dates
- dried apricots
- figs
- grapes
- mangoes
- papayas
- pineapples
- raisins
Most fruits are a good source of dietary fiber. Fiber is important for bowel regularity and for preventing constipation. Fiber may also help to lower blood cholesterol levels and to control blood sugar levels.
Fruits are also a good source of many vitamins and minerals. Vitamin C is found in high amounts in many
Parts of Plants and Their Functions
- The plant body is made up of several parts that have specific functions.
- The stem supports the plant and carries water and nutrients from the roots to the leaves.
- The leaves capture sunlight and use it to produce food through photosynthesis.
- The flowers produce pollen and seeds.
- The roots anchor the plant and absorb water and nutrients from the soil.
