Many grasses for example. Many crops. All plants that produce fruit. Fruit In fact, flowering plants all bear fruit---just maybe not fruit in the sense that you are used to. Not all fruit ---if going by the biological definition---are sweet or even edible. By the biological definition, a fruit develops from the ovary of a plant. Which doesn’t exactly sound that appetizing. Pumpkins, green beans, tomatoes---these all developed from the ovary of a flowering plant. These are all fruits. The term “vegetable” really isn’t used as a true biology definition. A lot of what grocery stores classify to be vegetables are other parts of plants----like leaves (think of lettuce) or stems (think of celery). and sometimes grocery stores just classify vegetables as plant structures that are generally not as...

    T he amazing process of photosynthesis a look around in nature is an absolute treat to our senses. We all enjoy the colors and fragrance of plants but seem to forget about their important contribution plants  are an absolute necessity for life on Earth. it is so because of the process of photosynthesis a closer look at a plant shows that it is firmly held in the soil by the help of roots these roots absorb water from the soil and through the tiny tubes transport it to the stem. After then transport to the leaves. The stem always  holds the leaves in  a way that they absorb maximum energy from sunlight a leaf is a very important part of the plant photosynthesis. The ultimate provider of food and oxygen occurs in the leaf. A leaf consists of a flat thin lamina. which is joined to the stem with the help of petiole. The flattened lamina provides large surface area for trapping sunlight a cross-section of the leaf shows the upper and lower layers of cells which a...
