Answer:
The correct answer would be organs and tissues perform these functions for the cells.
In multi-cellular organisms, similar cells work in integrity to form tissues which in turn form organs.
The organs together form an organ system.
The organ system performs specific functions with the help of specific organs and tissues.
In addition, the organs and tissues help all the associated to get food, air, and remove waste.
For example, blood vessels supply blood to each and every organ and tissue which then ensure that each cell gets food and oxygen.
Answer:
Photosynthesis is the process by which green plants manufacture their foods using the energy from the sun. Plants are the only living organism that have the ability to tap energy from the sun and use it to produce their food. The food produce by plants are used by plants and all other living organisms for survival. The herbivores feed directly on plants while carnivores feed on herbivores. The omnivores animals feed on both herbivores and carnivores. Thus, all living organisms on the earth depend on photosynthesis and on plants for the production of foods from which they derive the energy that they use to carry out their life activities.
Photosynthesis is essential to life on Earth as it provides organisms with energy, produces atmospheric oxygen, and contributes to biodiversity.
The process of photosynthesis is central to sustaining life on earth because it allows living organisms to harness energy from the sun and convert it into chemical energy in the form of glucose. This energy is then transferred through the ecosystem and used by heterotrophs for various biological processes, including growth and reproduction.
During photosynthesis, plants also produce oxygen, a by-product that is vital for aerobic respiration in most organisms. The oxygen we breathe and the food we eat are both direct products of photosynthesis, thus highlighting its importance in sustaining life on Earth.
The diversity of life forms we see today also owes much to photosynthesis, as the energy it captures has allowed organisms to evolve complex structures and thrive in different environmental conditions. As such, photosynthesis plays a major role in maintaining the global biodiversity.

Answer: D) Protista
Explanation:
The kingdom Protista includes organisms which are simple eukaryotic, they are usually composed of single cell or multicellular organisms. These organisms either live in water or in terrestrial habitats. Some of the organisms in the kingdom Protista exhibit characteristics which are similar to plants and animals. As, some organisms are parasitic like animals and others can conduct photosynthesis like plants in order to obtain food. Therefore, according to the above explanation kingdom Protista includes autotrophic, hetrotrophic, unicellular and multicelluar organisms.

hope it helped !! :))
Answer:
Water enters the plant through the root hairs and travels upwards in the stem vie the xylem, which is called capillarity.
Explanation:
Answer:
Prokaryotic cells have a ring-shaped nucleus, however it is not fully defined, and thanks to this, their DNA is found unlike eukaryotic cells, scattered in the cytoplasm, an example of a prokaryotic cell is a bacterium, which has Oval shaped

Hope I help!
The correct answer is binary fission.
It is the process by which prokaryotic cells produce new cells that are genetically similar to the parent cell. It is an asexual kind of reproduction.
it occurs in three main steps
1. DNA replication to make a set of two chromosomes.
2. Chromosome segregation where the two chromosomes separate.
3. Cytokinesis, a process in which a new plasma membrane begins to form in the center of the cell followed by the splitting of the cytoplasm into two, and two daughter cells are formed which are genetically similar to each other and to the parent cell.
