why do plants bear fruit?what are plant tissues?
The reason plants bear fruit is because it's a adaptation that allows them to spread their seeds in different locations. Animals, such as birds eat them and then disperse them in their droppings.
You have to be more specific as to your second question of, "what are plant tissues?"
Do you need to know what their made of?
I searched Google under the key words "fruit function plants" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps a little more. Thanks for asking.
Plants bear fruits as a means of reproduction and dispersal of their seeds. Fruits are produced by flowering plants and are designed to protect seeds as they develop and mature. When the fruits ripen, they often become more attractive to animals due to their color, taste, or fragrance. Animals consume the fruits and disperse the enclosed seeds through their digestive system or by carrying them to other locations. This process increases the chances of the seeds finding suitable conditions for germination and growth.
Now, let's move on to your second question. Plant tissues are groups of cells that work together to perform specific functions within a plant. There are three main types of plant tissues:
1. Meristematic Tissue: This tissue consists of actively dividing cells and is responsible for the growth of the plant. It is found in areas of the plant where growth is occurring, such as the tips of roots and stems.
2. Dermal Tissue: This tissue forms the outer protective covering of the plant. It helps prevent water loss and provides a barrier against pathogens. The outermost layer, known as the epidermis, often contains a waxy substance called cuticle.
3. Ground Tissue: This tissue makes up the majority of the plant body and carries out various functions, such as photosynthesis, storage, and support. Ground tissue can be further classified into three types: parenchyma, collenchyma, and sclerenchyma.
Parenchyma cells are involved in photosynthesis and storage of nutrients. Collenchyma cells provide flexible support to growing parts of the plant. Sclerenchyma cells, on the other hand, provide rigid support to mature parts of the plant.
Understanding the different types of plant tissues is crucial for comprehending how plants grow, develop, and function.
