Reproduction In Biology

There is a hanging question: What does it mean to be alive? For me it means everything. We should be thankful that God gave us life---almost everything like food.
Life science is the study about the way they respond to each other and in the world, it includes microorganism, plants, animals, and human beings. The characteristics of life are: all living things are made up of cell and it can be unicellular (one) or multicellular (many cells). They also reproduce, grow and develop, use and obtain energy, and lastly they should adapt and respond to their environment. Autotrophs are the producer and they can produce their own food while heterotrophs the consumer that get food from the environment. There are ten (10) fields of science these are:

Perpetual comes from the Latin word perpes/perpet- means never ending/ continuous. Here I learned how plants and animals reproduce even humans. I am the one who was assigned to report it and it’s so long that I already consumed one hour/ one session/ one class of ours, so our teacher cut it short. Here I tackled about asexual and sexual reproduction in plants and animals. Sexual reproduction in plants occur in flowering plants or angiosperm, where there are both male and female gametes. It happens thru pollination, and there are two types of pollination first is self-pollination and the second one is the cross-pollination. Self-pollination is when pollen falls from the stigma to the anther in the same flower while the cross-pollination needs the appearance of an animal like bees transferring pollen from one flower to another.

According to Ms. Zabalo’s report animals survive thru metabolism and there are two (2) kinds of metabolism this are: catabolism and anabolism. The catabolism breaks down larger molecules and releases energy while anabolism regulates smaller molecules. There are different metabolic processes that take place in some animals such as nutrients—the organic and inorganic nutrients. Organic nutrients are carbohydrates, proteins, fats, and vitamins and they synthesized within living organisms while inorganic nutrients are minerals and waters, and they are the one who supplies through digestion or from environmental sources. Gas exchange---Oxygen concentration in the cells  low, carbon dioxide  high, CO2 is a waste product that is released by the body. Blood circulation, homeostasis, excretion, immune system, hormone: chemical signal, and nervous system. Plants survive thru plant tissue and plant organs. Plant tissue, dermal tissue where it protects the soft tissues of plants and controls interactions with the plants ' surroundings like epidermis, stromata, etc. Under it are the ground and vascular tissue, ground tissue it can be neither dermal nor vascular part of the ground system and can be seen in the center of the stem or middle of the leaves. The vascular tissue enables the water, sugar and minerals made by photosynthesis to move to the different parts of the plant. It has two parts the xylem and the phloem. Plant organs are
