Plant Structure and Function




Plant Structure and FunctionThe primary structures or organs present in plants are the stems, leaves and roots. They are composed from teams of specialized tissues that possess structures suited for the jobs they carry out. The below summarizes the primary features of their functions and these structures. 

Structures

Leaves: Thin with a big surface area. Cells include chlorophyll in chloroplasts.

Stems: Long and cylindrical. Woody tissues - xylem and fibres (sclerenchyma) - add strength.

Include xylem and phloem (in Ďveinsí).

Roots: Branch extensively via the soil.

Root hairs - provide large surface area.

Contain xylem and phloem (in Ďveinsí).

Root tip - area of cell division.

Root cap - covers the root tip.

Functions

Short distances with regard to gases to diffuse.

Huge area for absorption of light.

Leaves are a plantís food factory. They are the principal site of photosynthesis, in which sugars are created from carbon dioxide and water, making use of sunlight energy which has been absorbed by chlorophyll.

Plant Cell Structure

Plant Cell Structure

Plant cells tend to be eukaryotic cells that are much like animal cells. As opposed to animal cells however, plant cells include structures including a plastids, cell wall and large vacuoles. The cell wall provides plant cells support and rigidity. Plastids aid in storing and harvesting required substances for that plant. Chloroplasts are plastids that are required for performing photosynthesis.

As a plant develops, its cells become specialized in order to carry out certain functions required for survival. Several plant cells synthesize and store organic products, while others assist to transport nutrients throughout the plant. You can find a number of crucial specialized plant cell types. Samples of specialized plant cells include:

Collenchyma Cells

Parenchyma Cells

Water Conducting Cells

Sclerenchyma Cells

Sieve Tube Members.

Plant Parts

Every part of a plant features a very important function. All plants generate flowers for the same purpose: to make seeds so one more plant can develop.

Leaves: These are the parts of the plant in which food is created by photosynthesis. Leaves consume water from the soil, carbon dioxide from the air and energy from the natural light. During photosynthesis, the leaves make use of light energy to modify carbon dioxide and water into food. (sugar)

Flowers: They are the reproductive parts of a plant. Flower petals and the flowers smell attract insects and bees to pollinate the flower.  Following pollination, the petals disappear and seeds develop in the part of a flower referred to as the ovary. The ovary itself generally becomes what we call the fruit.

Stems: These help the higher parts of plants. Dissolved nutrients and water through the soil move up the stem in a system of pipes. Food from the leaves travel lower stems to the roots. Stems also store food for that plant.

Different Types of Plants

Plants evoke images of lush, green vegetation. The number of plant varieties is staggering. Keep reading to know about different types of plants.

Plants have been around since a very very long period. Did you know you can find greater than 315,000 recognized species of plants? That is a whole lot. Plants are the only organisms that show apical dominance; they could be considered practically immortal, for that vast majority of them continue growing through their lifetime. Plants are also the only organisms that can perform photosynthesis the procedure by which environmental carbon dioxide.
