GENERAL HISTOLOGY

Detailed explanation-1: -Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast.

Detailed explanation-2: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Detailed explanation-3: -A cell can make its own food or get it from somewhere else. Animal cells must take food in from some other source. Plants, on the other hand, have the ability to make their own food through a process called photosynthesis.

Detailed explanation-4: -An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.

Detailed explanation-5: -Unlike animal cells, plant cells have a cell wall surrounding the cell membrane. Plant cells can be distinguished from most other cells by the presence of chloroplasts, which are also found in certain algae. Another important characteristic of many plant cells is the presence of one or more large vacuoles.
