Morphology is the study of science that deals with the form and structure of an organism. Morphology of leaves deals with the study of the structural features and parts of a leaf.
What is the morphology of a plant?
What is the general morphology and function of leaves?
What are the 4 features of a leaf?
- The leaf is a lateral dissimilar appendage of the stem.
- A leaf is always borne at the node of the stem.
- Generally, there is always an axillary bud in the axil of a leaf.
- It is exogenous in origin and develops from the swollen leaf primordium of the growing apex.
- The growth of leaf is limited.

What are tap root plants?
taproot, main root of a primary root system, growing vertically downward. Most dicotyledonous plants (see cotyledon), such as dandelions, produce taproots, and some, such as the edible roots of carrots and beets, are specialized for food storage.
What causes chlorosis in plant?
What causes chlorosis? Chlorosis occurs when a tree or shrub is lacking certain micronutrients, in many cases iron or manganese. Lack of micronutrients in a tree may reflect a lack of these nutrients in the soil due to poor fertility.
What’s a leaf margin?
The leaf margin is the boundary area extending along the edge of the leaf. There are lots of different types of leaf margins that are important for plant identification. The basic types of margins are: Entire: having a smooth edge with neither teeth nor lobes.
How many types of leaf margins?
Toothed leaf margins: 3 types
This covers three terms; serrate, dentate, and crenate. Serrate margins are leaf margins where the teeth are like those of a saw, continuous and forward pointing (like the sweet chestnut). Dentate margins have continuous teeth which point outwards (like the strawberry).
What is leaf margin?
This character refers to the structure or appearance of the margins of the leaves. Entire: the leaf margins are not toothed or divided in any way (smooth). Wavy: the leaf margins are not divided but curve up and down (undulate). Crenulate: the leaf margins are cut into small rounded teeth.
What is a leaf class 6?
Leaf is a thin, broad, green part arising from the stem. Leaves are present on branches of the plant which are attached directly to stem. Every plant have a large number of leaves.
What does a seed need to grow into a new plant?
Essentials. The beginning of the growth of a seed into a seedling is known as germination. All seeds need water, oxygen and the right temperature to germinate. Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth.
How deep do tap roots grow?
Intact taproots are usually largest just beneath the trunk and taper until they reach a depth of 0.5-1m, where they often divide into several smaller, but nevertheless downwardly growing, roots.
Why is my soil low in iron?
Possible causes of iron deficiency
Over or underwatering your plants in soil causes chlorosis and stress on plants. The soil has too much clay or is too wet causing oxygen supply in the roots to stagnate. The substrate contains too much phosphorus. The root temperature is low.
How do you add nitrogen to soil?
You can increase nitrogen in soil by adding nitrogen-rich fertilizer, composted manure, processed plant-based soil amendments, homemade compost, and even by planting certain crops that can pull nitrogen down into the soil from the atmosphere. These are all great sources of nitrogen for plants.
Where is the base of a plant?
A ‘base’ is defined as the ‘lowest or bottom part of an object on which it stands’ or the ‘main part to which other parts are added’. In biology, ‘base’ means the part of a plant or animal organ that is near the point of attachment to the ground or to a more basal part of the body.
What is a plant lobe?
Lobes are projections of the blade with gaps between them (these gaps, however, do not reach the middle vein). Maple leaves, with their distinct pointed projections, are good examples of simple lobed leaves. Unlobed simple leaves have plain, rounded shapes without any projections.
What is tip in leaf?
The tip of the leaf blade is called leaf apex.
What are plants Grade 5?
Plants are living things which cannot move from place to place and need air, water,soil and sunlight to live. Plants are of different shapes and sizes.
What are the 4 functions of a stem?
(i) It supports branches, leaves, flowers, and fruits. (ii) It transports water and minerals from the roots to the leaves and other parts of plants. (iii) It transports food from leaves to different parts of the plant. (iv) It holds the plant upright.
How do you make smoke water for seed germination?
You can also use smoked vermiculite to quickly make small batches of smoke water, ideal for if you’re only germinating a few seeds. Simply add a teaspoon or so of vermiculite to a small jar of water, shake well, and leave to soak for half an hour.
What tree has the strongest roots?
Shepherd’s tree (Boscia albitrunca), native to the Kalahari Desert, has the deepest documented roots: more than 70 meters, or 230 feet, deep. Their depth was discovered accidentally by drillers of groundwater wells.
