The answer should be Rhizoid, because rhizome is "root-like STEM"
There are quite a lot of weird and unusual trees and plants that have been born as a result of evolution over millions of years. The kauri tree in New Zealand for instance, is weird to look at as it has thick trunks and very thin branches. The quiver tree in Namibia is yet another wonderful marvel of nature, which looks more like a giant colored flower.
Halfmens in South Africa are yet another impressive species of trees which more like the trunk of an elephant. These weird species of trees tend to have other names as well due to their unique physical characteristics.
There are a number of plants that can be grown inside without the need of any direct sunlight. The most popular among all of these plants include the famous ‘mother in law tongue’. This plant has a peculiar name and I believe that it gets it through the sharp edges that it has. This plant tends to store water in the foliage.
Hence, over watering can result in its roots getting rotten. Moreover, this plant is not suitable to be grown inside in case you own pets. This is because its ingestion can upset their stomachs quite bad. There are more, like the lucky bamboo and Peace Lily.
The banana tree is not referred to as a tree. Though we might call it a tree in non-technical terms, in technical terms, however, it is herb. The prime reason why it is not called a tree is because it never forms woody stems the way a normal tree does. Instead, it forms talks. Banana plants in warm climates tend to grow throughout the season.
Hence, they can be grown both in winters and summers. In botanical terms, the banana plant is referred to as herbaceous plant or herbaceous perennials. Again, this is because its stem does not have woody tissues in it.
The prime reason why humans cannot produce their own energy other than from eating food isbecause of the anatomical differences that humans and other animals have in comparison to the plants. Humans tend to get their energy by breaking down the food that they eat.
The plants on the other hand make their own energy using sunlight, carbon-dioxide, and other nutrients from the soil. Hence, comparing the two would not make enough sense because both are formed differently and have been developed differently by nature. Other ways of making energy might be developed as research does goes on into this topic.
Talking about easy topics, there are no easy topics related to botany. At least, there is no easy topic that would be available for a thesis. Before starting your thesis work, make sure that you are doing it in an area in which you have a great level of understanding. Otherwise, you might get stuck with it for a year or two.
Apart from that, make sure to conduct a good level of investigation. There are various good articles available on google that tell you how to choose a thesis topic. Go through these articles, and you will be good to go.
Leaf spots is more like an umbrella term that is used for the spots that appear on the leaves. There are various reasons for the white spots that you can see on the leaves. The prime reason is the sooty mold. The sooty mold is a type of fungus that tends to grow on a range of leaves on the sugary substance that different insects leave behind after feeding on the leaves.
This fungus does not directly harm the leaves, however they do cover up the area that can be used for photosynthesis. Apart from that, powdery mildew is another fungus that appears as white spots on leaves.
Both disciplines are totally different from each other and in principle, none of them is better than the other. In fact, both tend to have their own unique challenges, its own areas of research, and own topics of interest. Whether one chose botany or zoology would completely depend on the individual himself/herself and on his/her primary interests.
Those people who do not carry significant interest in either of these fields might find them quite dry and boring. On the other hand, those who love these areas of science can do great in either of those. In principle, both are different and cannot be compared.
Botany is the study of plants and the way plants interact with the environement around them. In straightforward terms, Yes, Botany is of extreme importance for us as it teaches us a lot of different things about the nature. Without understanding botany, plantation would not be possible which would mean less effective farming and hence, a global famine.
Botany also helps scientists understand how various plants can be differentiated from one another both in terms of their genetic structure and other properties/functioning. It is indeed one interesting area of science and is specifically good for students having keen interest in plants.
The correct answer to this question is A.
Phloem and xylem are complex tissues that perform transportation of food and water in a plant. They are the vascular tissues of the plant and together form vascular bundles. Xylem is formed by tracheary elements like tracheids and vessels predominantly. There are a variety of other cells giving it the status of complex tissue. Primary xylem originates from the procambium during primary growth while secondary xylem has its origin in vascular cambium during secondary growth.
Phloem has sieve tubes, companion cells, bast fibers as its elements. Phloem originates from meristematic cells in vascular cambium- primary phloem from apical meristem and secondary phloem from vascular cambium.
