Plants and animals worksheets.
Plants and animals are two major categories of living organisms that make up the diverse ecosystems on Earth. They are part of the biological kingdom known as “life” or “living organisms.” Here’s a brief overview of each category:Plants and animals worksheets downlode no free pdf .
Plants:
Definition:
Plants are multicellular, eukaryotic organisms that belong to the kingdom Plantae. They are characterized by their ability to photosynthesize, which means they can convert sunlight into chemical energy (usually in the form of glucose) through the process of photosynthesis. This process involves the use of chlorophyll, a green pigment found in plant cells.
Key Features:
Cell walls made of cellulose.
Stationary and rooted to the ground.
Reproduction through seeds, spores, or other means.
Play a vital role in ecosystems by providing oxygen, food, and habitat for animals.
Include a wide variety of species such as trees, shrubs, grasses, flowers, and algae.
Animals:
Definition:
Animals are also multicellular, eukaryotic organisms, but they belong to the kingdom Animalia. Unlike plants, animals are heterotrophic, which means they cannot produce their own food and must obtain it by consuming other organisms.
Key Features:
Lack cell walls, instead having flexible cell membranes.
Are mobile and capable of various forms of locomotion.
Reproduction through sexual or asexual means.
Exhibit a wide range of behaviors, from simple reflexes to complex social interactions.
Include a vast array of species, from microscopic organisms like protozoa to large mammals like elephants.
Plants and animals together form the foundation of terrestrial and aquatic ecosystems, and they interact in various ways to maintain the balance of life on Earth. Plants provide food and oxygen for Plants and animals, while animals can disperse seeds and help with pollination, among other ecological interactions. Together, they are essential components of the Earth’s biodiversity and play critical roles in sustaining life on our planet.
