Question

6 differences between responses in flowering plants and mammals

Answer 1

BASIS FOR COMPARISON PLANTS ANIMALS

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 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. They have proper nervous system and response to any stimuli in a fraction of seconds, so they are regarded as highly sensitive.

Answer 2

Explanation:

• Mammals and plants both react to outside stimuli.
• Plants respond slowly to stimuli, whereas animals respond slowly.
• Only particular stimuli, typically light and touch, cause plants to respond.
• Animals respond to a variety of stimuli, including light, heat, pressure, smell, and others.Plants lack a spinal cord and brain.
• Animals respond to stimuli using both hormones secreted by the endocrine glands and electrical impulses produced by the nervous system.
• Animals' brains and spinal cords determine how they react to stimuli.

Some extra common differences:

• While plants can produce their own sustenance using carbon dioxide and water in the presence of sunlight the animals cannot, plants cannot move like animals can.
• Creatures rely on plants and/or other animals to provide for their nutritional needs.
