Question

write short note on plant body and animal ​

Answer 1

Explanation:

All but a relatively few plants are multicellular, and the majority have bodiescomposed of two major systems: the root system and the shoot system. The former is usually underground, and the latter above ground. To succeed and grow simultaneously in two such entirely different environments—air and soil—requires a myriad of adaptations, starting with cellular modifications into specialized kinds oftissues (groups of similar cells that are organized in a structural and functional unit) followed by development of organs (structures composed of several kinds of tissues grouped in a structural and functional unit). The acquisition of form and structure is called morphogenesis and is a highly orchestrated procedure controlled by the DNA of the plant cells but influenced as well by the environment.

Animals are multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from 8.5 millionths of a metre to 33.6 metres (110 ft). They have complex interactions with each other and their environments, forming intricate food webs. The kingdom Animalia includes humans, but in colloquial use the term animal often refers only to non-human animals. The study of non-human animals is known as zoology

Answer 2

Meaning

• Plants are green in colour due to the presence of the chlorophyll and are able to prepare their own food with the help of sunlight, water and air. They are known for providing oxygen to the atmosphere.
• Animals are the living organisms which feed on the organic material and are known to have a specialized system in their body like the nervous system, reproductive system, sense organs, which make them unique from the other forms of life.

Movement

• Plants do not have the ability to move from one place to another, as plants are rooted into the ground, exceptions are Volvox and Chlamydomonas.
• Animals can move from one place to another freely, and exceptions are Sponges and Corals.

Mode of nutrition

• Plants have chlorophyll, due to which they have the capability to prepare their own food and are known as autotrophs.
• Animals are the heterotrophs, as they depend on plants for their food, either directly or indirectly.

Storage of food

• Plants do not have the digestive system, and the storage of food (carbohydrate) takes place in the form of starch.
• Animals have the proper digestive system which support the food in digesting and absorbing nutrition from it, the food (carbohydrate) is stored in the form of glycogen.

Respiration

• Plants take in carbon dioxide and release oxygen into the atmosphere, exchange of gases occurs through stomata.
• Animals take in oxygen and release carbon dioxide into the atmosphere, which occurs through lungs, gills, skin, etc.

Cellular structure

• The cellular structure of plants contains the cell wall, chloroplast, plasmodesmata, plastids and other different organelles.
• The cellular structure of animals does not have cell walls, though other organelles like the tight junction, cilia are present.

Growth

• The growth of the plants takes place throughout the life, the meristematic system present in the tip of roots and stems supports the growth.
• The organs and organ system supports the growth in animals and is definite.

Reproduction

• Reproduction of plants takes place asexually like by budding, vegetative methods, spores, wind, or through insects.
• Some lower animals like algae reproduce asexually while higher animals reproduce sexually.

Response

• Plants show the response to stimuli like touch, light, though are less sensitive due to the absence of the sense organs.
• Animals have proper nervous system and response to any stimuli in a fraction of seconds, so they are regarded as highly sensitive.
