Answer:
Euglena is a single celled organism. It belongs to Kingdom Protista. Euglena is a eukaryotic organism that exhibit characteristics of both plants and animals. Some species of Euglena are photoautotrophs like plants which means they have ability to trap sunlight to produce food by the process of photosynthesis. Whereas, some species are heterotrophs like animals which means they obtain food by feeding on other organisms.
If scientists remove all of the chloroplasts from a Euglena, it will not be able to perform photosynthesis because chloroplast is an organelle that contains light sensitive pigments named as chlorophyll. Chlorophyll traps light energy from sun. Sunlight energy, along with carbon dioxide and water produces food in the form of glucose in plants and other photoautotrophs.
Answer:
<h2>A
</h2>
Explanation:
1. The cell is present in some type of cells. It is found in plants and bacteria and some others. It is present or found outside the plasma membrane.
2. The functions of cell wall are that it provides tensile strength and protection to the cell against many type of stress. It also plays very important role in many others protections for the cell. There are two layer, named as primary cell wall and secondary cell wall.
3. Composition of Plant cell walls is that they are primarily made of cellulose. Cellulose fibers are linear long polymers of around 100 molecules of glucose. These fibers cluster into bundles, known as or called microfibrils. In plants the microtubule cytoskeleton are present, and there function is that they directs the orientation of cell wall as in which orientation cellulose is deposited in the cell wall.
B I don't belive plant life is that important to this question
Answer:
The correct answer will be option E.
Explanation:
The features given in the question are the characteristics features of the group of bacteria belonging to Cyanobacteria.
These Cyanobacteria are the prokaryotes which are capable of synthesizing the food through a process called photosynthesis. These bacteria use sunlight as their energy, use water and air to synthesize food. They under anaerobic condition synthesize the nitrogen in special structures called heterocyst, a characteristic feature of cyanobacteria.
Thus, the features given in the question are:
1. contain photosystems to carry out photosynthesis.
2. producing oxygen
4. contain phycobilins
6. Hetrocysts: nitrogen-fixing structures.
7. The ancestor of plant chloroplasts.
Thus, option E is the correct answer.
