- The structure of DNA
- Sequence of mitotic division
- Hollow sac having an opening
- Eukaryotes
- b
-
Cleavage means rapid repeated mitotic (cell) divisions of the zygote after fertilization.
The structure of DNA is not cleavage.
Eukaryotes is a type of organism.
- Platyhelminthes
- Nematode
- Porifera
- Mollucsa
- d
-
Cephalopods is like octopus, squid, cuttlefish.
- An Embrye
- A Gamete
- A Foetus
- A Zygote
- d
-
After fertilization, when the male gamete (sperm) and female gamete (egg) fuse, they form a single cell called a zygote. This zygote is the first cell of a new organism and later develops into an embryo and then a foetus.
- Enzymes
- Glycerols
- Coenzymes
- Polynucleotide
- c
-
Coenzymes are organic molecules that bind to enzymes and help in chemical reactions.
- Is necessary for the survival of the individual
- Cause new notations to occur in the offspring
- Promotes genetic variability among offspring
- Allows larger no of offspring to be produced

- Cytoplasm
- Centromere
- Atmosphere
- Cytoplasm
- b
-
Centromere means the middle pin of chromosome.
The shape of chromosome depends on the position of this pin.
If it is in the middle then chromosome looks like X-Shape and if it is near the end then chromosome looks like V or L shape.
- The male gametangium
- The female gametangium
- Rhizoids
- Ovum
- c
-
Male Gametangium produces male sex cells.
Female Gametangium produces female sex cells.
Ovum is a female sex cell.
- Flagella
- Cell wall
- Capsule
- Pilli
- d
-
Pili are tiny hair-like parts on bacteria. They help one bacterium connect with another to pass genetic material during conjugation.
- Osmosis
- Exocytose
- Hydrolysis
- Phagocytosis
- d
-
White Blood Cells protect our body.
Osmosis is movement of water only.
Exocytose throw things out of the cells.
Hydrolysis means breaking of something by using water.
- Disulphide
- Hemoglobin
- Amino Acid
- Peptical Bond
- b
-
Hemoglobin has four protein parts, each part can hold oxygen and together they carry oxygen in blood.
Disulphide, Amino Acid and Peptical Bond are parts of proteins, not whole proteins.
