A. 1.2 per m2 ✓ B. 2.4 per m2 C. 4.8 per m2 D. 9.6 per m2 The answer to the question is: A. 1.2 per m2 Calculating Plant Density To calculate the density of the plants in the field, we can use the…
THE PLANTS THAT GROW IN DESERTS OR VERY DRY AREAS ARE REFERRED TO AS
A. mesophytes B. hydrophytes C. epiphytes D. xerophytes ✓ The answer to the question is: D. xerophytes Xerophytes are the plants that grow in deserts or very dry areas. These plants have adapted to survive in arid conditions by reducing water loss and efficiently…
EXPLORING THE CREATION OF TRANSGENIC PLANTS
Making transgenic plants involves the process of introducing foreign genes into the genome of a plant in order to confer specific traits or characteristics. This technology has revolutionized agriculture by enabling the development of crops with improved resistance to pests,…
OVERVIEW OF TRANSGENIC PLANTS
Transgenic plants, also known as genetically modified (GM) plants, are created by introducing new genes from one organism into another using biotechnology. This process allows scientists to modify the genetic makeup of a plant to achieve specific desired traits, such…
MECHANISM OF TRANSPORTATION IN PLANTS
The lower plants All the plants from the single-celled Chlamydomonas, bacterium, Phacus to the simple multicellular Spirogyra, Funaria (Bryophyta) that lack conducting vessels use their cytoplasm for the movement and distribution of materials. Most of these lower plants live in…
POLLINATION IN PLANTS
Pollination is defined as the transfer of mature pollen grains from the anthers of one flower to the mature stigma of the same flower or another flower of the same plant or closely related species. Pollination is the first step…
FERTILIZATION IN FLOWERING PLANTS
Immediately after pollination, fertilization follows. Fertilization is the union of male and female gametes to form a zygote. In a flower, the male gametes develop from the pollen grains while the female gametes develop from the ovules which are retained…
EXTERNAL FEATURES OF FLOWERING PLANTS
The flowering plants form a group of plants known as Angiosperms. They are characterized by the possession of flowers for sexual reproduction. They bear flowers in their various breeding seasons and after pollination and fertilization, seeds are formed enclosed in…
EXCRETION IN PLANTS
There are no special excretory organs or systems in plants. The plants as living things do carry out excretion. Elimination of certain waste takes place through the stomata and lenticels. The main waste products of plants are water from transpiration…
REPRODUCTIVE SYSTEMS IN PLANTS
The flower is the reproductive structure of flowering plants. It contains the male and female sex organs which enable them to exhibit sexual reproduction. Fertilization inside the flower often leads to the production of seeds which are capable of germinating…
FLORICULTURE
Floriculture is simply defined as the production and management of ornamental plants such as trees, shrubs and flowers. In other words, floriculture involves the growth, care, uses and marketing of some flowering plants, trees and shrubs. Beautiful trees or flowering…
ALLEY CROPPING
This is a system which involves the growing of food crops in spaces between hedge-rows of trees or shrubs, which must undergo regular pruning every five or six weeks. The species of plants that can be used for alley cropping…
CLASSIFICATION OF PLANTS
Plants are generally classified based on three major criteria. These are: Botanical classification. Agricultural classification. Classification based on life cycle. BOTANICAL CLASSIFICATION OF PLANTS Plants are generally classified through the botanical method and the use of binomial system. The…
SUPPORTING TISSUES IN PLANTS
Plants generally are known to possess supporting tissues which give them definite shape, strength, rigidity and resistance against external forces such as wind and water to which they are continuously subjected. Types of Supporting Tissues in Plant The main…
