Robert Hoole used the name cells to describe their shape and pattern.
Cells - are little rooms enclosed by a wall (just like cells).
Hope it helped,
Happy homework/ study/ exam!
Coniferophyta
Explanation:
Plants and trees belonging to coniferphyta are gymnosperms which are vascular plants with unprotected or naked seeds. These are called conifers because they bear male and female cones produced by the sporophytes on the same tree . The female conifers have many seeds on the cone scales.
These cones have spores which undergoes meiosis and produce male and female gametes respectively. Male gametes with pollen grains produces sperm cells and female gametes produce egg cells inside the ovules.
During the spring season with winds blowing, pollen released from the male cone disperses on the female cone present on the same tree.
Upon reaching the female cone, the sperms in the male gametes will fertilize the egg cells in the female and will fertilize to form zygote. This zygote will develop into an embryo in the ovules and later develop into seeds.
When these seeds fall on the ground, they get germinated into a new conifer. Thus dispersal of the seeds is taken care of by the seeds itself without the production of any fruit.
Do not use the car frequently because of its environmentally damaging gases. Instead of using your car you can use bicycles.
Everyone’s body is made of the same basic stuff. All living things, large or small, plant or animal, are made up of cells. Most living things are made up of one cell and they are called unicellular organisms. Many other living things are made up of a large number of cells that form a larger plant or animal. These living things are known as multicellular organisms. Water makes up about two thirds of the weight of cells.
Cells are very small; most cells can only be seen through a microscope. Cells are the smallest living units that are capable of reproducing themselves. Each cell in your body was made from an already existing cell. All plants and animals are made up of cells. In this article, we will talk about the cells that make up You.
pre All the parts of your body are made up of cells. There is no such thing as a typical cell. Your body has many different kinds of cells. Though they might look different under a microscope, most cells have chemical and structural features in common. In humans, there are about 200 different types of cells, and within these cells there are about 20 different types of structures or organelles.
