<h2>
Vascular and Nonvascular Plants </h2>
Explanation:
Kingdom Plantae on the basis of vasculature is divided into two groups-vascular and non-vascular plants
.
- <u>Vascular plants </u>or tracheophytes have a proper tissue-level organization and true shoot and root structures like leaves, stem, flowers, root etc
- The tissue system or vasculature of vascular plants compromises of vascular tissues like tubular vessels – xylem and phloem
- The xylem transports nutrients to various parts of the body from the leaves.
- Phloem conducts water and other nutrients from the roots to various parts of the plant
.
- These are flowering plants that include the phanerogams – angiosperms and gymnosperms and bears flowers and fruits like the cedars, pine, clubmosses, lilies, sunflower etc.
- Dicots are with tubular vasculature.
- Non-vascular plants or bryophytes with an absence of proper tissue-level organization and true shoot or root systems
- <u>Nonvascular plants</u> are small. Their transport mechanism is poor due to lack of vascular tissues
- These plants are lack proper shoot or root system.
- It includes mosses, hornworts etc.
- Monocots are plants with scattered tube-like vessels

Well the red blood cells ( erythrocytes) contain the oxygen carrying pigment known as haemoglobin. Hence RBCs carry oxygen to every cell ion the body.
The white blood cells ( leukocytes) form the cell mediated defence system of the body, they kill microbes and foreign particles either by phagocytosis or lysozymic reactions.
The platelets (thrombocytes) help in the blood clotting process.
This is my comparism of tne blood components.

Answer:
An intrauterine device, also known as intrauterine contraceptive device or coil, is a small, often T-shaped birth control device that is inserted into the uterus to prevent pregnancy. IUDs are one form of long-acting reversible birth control.
Answer:
The correct option is A. Cooler, more dense material sink while warmer, less dense material rises.
Explanation:
Convection can simply be described as the transfer of heat energy among molecules or substances. Convection will occur if molecules of liquid or gas are given rough supply of heat. Hot liquids or gases would have the following properties:
- Their density would be less.
- They would have the ability to rise.
Whereas the cooler molecules will have the following properties:
- Their density would be more than the hot molecules.
- They would have the ability to sink.
