Answer:

Bryophyta. (Ans. B)

Explanation:

Bryophytes are consisting 3 division of embryophytes (non vascular land plants) which are; mosses, liverworts, and hornworts. They prefer to live in moist places, and can live to drier places also. Bryophytes reproduce with the help of spores, and they do not produce seeds, and flowers.

Bryophytes are gametes dominant in nature, it means they are longer lived, prominent plant is the haploid gametophyte. The sporophytes diploid become visible only occasionally, and nutritionally depends and attached to the gametophytes.

2. If a cell has a very large amount of ribosomes attached to its rough
Otrada [13]

Answer:

Protein

Explanation

Ribosome and Rough E.R are organelles  in the cell.

E.R are extensive membranes (which are continuous with the nuclear membrane) that exist as flattened compartment in the cytoplasm.These compartment form sacs in the cytoplasm. The sacs are interconnected with one another to form a complete system  called the reticulum.

Based on structure two types of E.R exists -the Smooth E.R and the Rough Endoplasmic reticulum.The later is called rough because of Ribosomes attached to its outer membrane. the smooth lacks ribosomes attachment on its outer membrane. Ribosomes are the site of Protein synthesis in the cell.

They are small in number and are made up of RNA and protein.Generally the protein  synthesised  in the Ribosomes,are moved into the sacs in the R.E.R,where they are modified.They are eventually budded off in vesicles which form the Golgi bodies

Concerning proton movement in mitochondria and chloroplasts, the __________ have a __________ H+ concentration. Choose one: A. l
umka2103 [35]

Answer: The answer is D - Intramembrane space in mitochondria; high

Explanation:

Mitochondria is an organelle in the cell, it is known as the power House of the cell because of its role in the storage and production of energy. During electron transport chain the proton pumps generate a proton gradient which is stored in form of energy.

During proton pumping and electron transfer the electrons are passed down the chain from the matrix to the inter membrane of the mitochondria. The electrons move from higher concentration of level to lower energy level. Some of these are used to pump Hydrogen ions (H+), moving them out of the matrix into the inter membrane space.

The Intramembrane space of the mitochondria therefore has a a high concentration of Hydrogen ions (H+).

I hope this helps.
