<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
.
The endoplasmic reticulum is an organelle that is responsible for the synthesis of lipids and the modification of proteins.
To calculate the mass of a single atom, you would need to add up the protons and neutrons of a single atom.
Answer: In Meiosis,chromosomes in a diploid cell resegregate, to give four haploid cells. Genetic diversity takes place during this early step of meiosis. DNA replication takes place before Early Meiosis commence. Pairing of homologous chromosomes which forms synapses is unique to Meiosis.
Explanation: Meiosis is a type of cell division which aides the formation of reproductive materials like the GAMETES SUCH AS SPERM CELLS AND EGGS,During Meiosis cell division takes place which reduces the number of chromosomes in the parent cell by half and produces four daughter cells, Meiosis is essential to guarantee genetic diversity in living organisms.
