The Stem supports the plant and carries water, nutrients, and plant chemicals up and down to all parts of the plant. The Leaves have little openings that let air and water come and go. They also catch energy from sunlight and use it to turn the air and water into food. The Roots are hidden underground, but are very important to the plant. They also suck up water and

Adaptations of plants in different habitats. 1. Plant adaptations in the desert. The desert is a dry area with scarcity of waters thus the plants there have small leaves and many spines which help them to conserve water. The leaves have thick waxy skins which help to retain water for a long time. There are leafless plants that store water in ...
ADVERTISEMENTS The following points highlight the nineteen essential features of ferns. 1. Ferns are seedless vascular plants of humid tropics and temperate areas. Some ferns live under sub-arctic conditions as well. 2. They constitute the largest living group of primitive vascular plants with over 10,000 species. Ferns once dominated the earth in carboniferous period (about

Objective. Our objective is to study the external features of Monocot and Dicot plants. The Theory. Flowering plants, also known as Angiosperms, are the most diverse group of land plants in the world, with at least 2,60,000 living species classified into 453 families. (The word Angiosperm finds its origin from two Greek words angio meaning covered and sperma meaning seed.

Leaf Scar Heart-shaped scar on twig where last years leaf grew. Node Growth region on stem.Region around bud or leaf stem. Bundle Scar Tiny bumps in leaf scar where veins enter the leaf from the stem. Terminal Bud Bud on end of a branch, where all of next years length (of branch) is added. Lateral Bud Small buds along length of branch that develop into leaves, lateral branches, or flowers.
Terrestrial plants share a few defining characteristics, structural as well as functional. Perhaps the most basic shared feature of most plants is their division into shoots and roots. The separation between these two portions of the plant came about during the evolutionary move from an aqueous environment to a terrestrial one, and each part is ...
Plant leaves are adapted for photosynthesis and gas exchange. Roots absorb water and mineral ions through root hair cells and are transported up the plant by the xylem.
