A crop is a plant grown for a selected objective. Crops like animals reside issues. As livings, they’ve varied components which allow them perform their every day life course of.
Plant life-form schemes represent a approach of classifying vegetation alternatively to the odd species-genus-family scientific classification. In colloquial speech, vegetation could also be labeled as bushes, shrubs, herbs (forbs and graminoids), and so on.
Crop vegetation consists of two primary components that are: the shoot system and the foundation system.
FUNCTIONS OF DIFFERENT PARTS OF A PLANT
The basis half is the a part of the plant contained in the soil. Now we have two sorts of roots. The faucet root and fibrous root. The faucet root consists of 1 main root from which varied minor branches come up whereas the fibrous root consists of quite a few related high quality roots all of which grows from the bottom of the plant.
FUNCTIONS OF THE ROOTS
They anchor [holds] the plant firmly to the bottom.
They soak up water and mineral salts from the soil and passes them to the stem.
They serves as storage organs in some crops e.g cassava.
The stem bears the leaves, buds, flowers and fruits. The features embody:
It helps the leaves, flowers and fruits
It conducts water and minerals salts in addition to manufactured meals to completely different components of the vegetation.
In some vegetation, the stem serves as a storage organ e.g. sugar cane.
The leaf is normally hooked up to the stem by a leaf referred to as the petiole and a blade referred to as ‘’lamina’’. A typical leaf comprises veins by means of which water, plant meals and mineral salt cross. The leaf manufactures meals and transfers it to the stem. All inexperienced vegetation are able to producing their very own meals by a course of referred to as photosynthesis within the presence of daylight.
It carry out the next features:
The leaves manufacture meals for the plant.
Some leaves function storage organs e.g. as in onions.
The flower is the reproductive a part of flowering vegetation. It’s the area the place the female and male organs produce the pollen grain and ovary respectively. The flower comprises the ovary which develops to kind fruit after pollination and fertilization. The ovules inside it develop to kind the seeds. Pollination is the switch of pollen from the anthers to the stigma.

TYPES OF CROP PLANT FORM
1. Monocotyledonous crops: these are E.g. All cereals & Millets, They normally have slim and lengthy leaves they usually embody sure households of grasses like: orchids and lilies. Palms e.g. coconut palm, oil palm, raffia palm, and royal palm are the frequent bushes on this group. Maize, guinea corn, millet, rice and wheat are the meals crops on this group of vegetation. Sugar cane can also be on this group and it’s industrial.
2. Dicotyledonous crops: these are crops which have two cotyledons within the seed. e.g. all legumes & pulses. This group has broad leaves not like the monocotyledons whose leaves are slim, and lengthy. Cashew, cotton and cocoa are the economic crops on this group. Tress like kola, grape fruit, guava tress, paw-paw, mango, silk cotton can also be discovered on this group. Most greens like: ewedu, okro, melon, cowpeas, yam and candy potatoes additionally belong to this group.
Variations between monocotyledonous and Dicotyledonous vegetation
|They’ve one cotyledon seed||They’ve two cotyledon seeds|
|The leaf has parallel veins||Their leaf has branching veins|
|their stem has bundles of vascular tissues scattered all through the stem||Their stem has bundles of vascular tissues organized in a hoop|
