A- Annelid is a round segmented worm distinguished by its body structure, containing 16,500 species.
B- The Blastopore usually develops in anus and mouth.
C- Casparian Strip is a water impermeable made of a ring of wax located in the endoderm cells of plants. It also blocks the flow of water in or out of the cell wall.
D- Watson and Crick deduced that Deoxyribose Nucleic Acid (DNA) is a double helix, which is that consists of nucleotide monomers.
E- Echinoderm is a slow moving marine deuterosome with a water vascular system such as a sea star.
F- Fetus is the developing mammal that has the major structures of an adult from 9th week of gestation until birth.
G-An organelle in eukaryotic cells consisting of stacks of flat membranous sacs that modifies store and route products of the endoplasmic reticulum and synthesize some products known to be the Golgi apparatus.
H-Haploid chromosome is a cell containing only one set of chromosomes.
I-Invertabrea is an animal without a backbone such as a crab.
J-James D. Watson is an American Biologists who is pne of the co-discoverers of the DNA structure along with Francis Crick.
K-A change in activity or turning rate in response to a stimulus is called Kinesis.
L- The Large intestine is located next to the small intestine. It is the last part of the digestive system in the final stage of the alimentary canal in in the vertebrates animals and functions by absorbing water from the remaining indigestible food matter and then to pass useless waste materials from the body.
M- Mold is also known as the informal way to say fungus, growing by producing haploid spores.
N- The Nucleus in a cell is also known as the "control center" a membrane enclosed organelle, found in eukariotic cells that functions to mainain the integrity of the genes and to control activities of the cell.
O-A female gametocyte or germ cell involved in reproduction is an Oocyte, also known as ovul or egg cell.
P- Photosynthesis is the process of converting light energy to chemical energy. This process occurs in plants and some algea. The general equation for photosynthesis is 6H₂O + 6CO₂ -----› C₆H₁₂O₆ + 6O₂
Q-
R- Complex of RNA and protein which are found in every cell are the Ribosomes which function in the expression of the genetic code from nucleic acid into protein in the process called translation.
S- A Seed is a small embryonic plant enclosed in a covering called a seed coat.
T- In mitosis the process Telophase is when the chromosomes sets assemble at opposite poles, then a nuclear envelope reforms around each set and cytokenises follows.
U- There are many types of Urchins but s sea urchin in specifically is a spherical sea creature with a spiny exterior.
V- A Virus is transmitted almost by anything, it spreads and is microscopic infection. Basically it's in infection that spreads in cells.
W- The structure for Water is H₂O.
X- In vascular plants Xylem is one of the transport tissue and phloem being the other.
Y- A eukaryotic microorganism in the kingdom Fungi is known as Yeasts which dominates the fungal diversity.
Z- The first stage of an organism is considered to be a Zygote containing only one cell.
