Headline:
"Understanding Gamete Formation and Cell Division in Heterogametic Species"
Key Points:
Types of Gametes: Gametes are of two types - male and female - in all heterogametic species.
Haploid Nature: Gametes are always haploid, regardless of whether the parent plant is haploid or diploid.
Haploid Parent Process: Haploid parent organisms produce gametes through mitotic division.
Organism Classification: Organisms like monera, fungi, algae, and bryophytes have a haploid plant body, while pteridophytes, gymnosperms, angiosperms, and most animals, including humans, are diploid.
Meiotic Division in Diploids: Diploid organisms possess meiocytes (gamete mother cells) which undergo meiosis to produce haploid gametes.
Result of Meiosis: Meiosis ensures each gamete has one set of chromosomes, maintaining genetic stability in species.

➩ The end of the T-wave marks the end of systole.
➩ Counting the number of QRS complexes that occur in a given time period, one can determine the heart beat rate of an individual.
➩ A patient is connected to the machine with the three electrical leads (one to each wrist and to the left ankle).
➩ P-wave represents the electrical excitation (or depolarisation) of the atria, which leads to the contraction of both the atria.
➩ QRS complex represents the depolarisation of the ventricles.
➩ T-wave represents the return of the ventricles from excited to normal state (repolarisation).

4. Free Central: Ovules on the central axis; no septa.
- Example: Primrose.
5. Basal: Single ovule at the base of the ovary.

Kingdom Protista: Key Notes for NEET 2025
1. Chrysophytes (Diatoms & Desmids)
- Found in freshwater and marine water; float passively; photosynthetic.
- Diatoms:
- Cell walls form two overlapping silica shells (like a soap box).
- Walls are indestructible, leading to diatomaceous earth deposits.
- Uses of diatomaceous earth: polishing, filtration of oil & syrups (gritty nature).
- Chief producers of the ocean ecosystem.
2. Dinoflagellates
- Mostly marine and photosynthetic.
- Pigmentation varies: yellow, green, brown, blue, or red (depends on pigments).
- Cell wall: Stiff cellulosic plates on the outer surface.
- Two flagella: one longitudinal, one transverse in furrows.
- Red Tide: Rapid multiplication of Gonyaulax causes water to appear red; toxins may kill fish.
3. Euglenoids
- Found in stagnant freshwater; no cell wall but have a protein-rich pellicle (flexibility).
- Have two flagella (short and long).
- Dual nutrition:
- Photosynthetic in sunlight.
- Heterotrophic in darkness (predates small organisms).
- Connecting link between plants and animals.
- Pigments similar to higher plants. Example: Euglena.
4. Slime Moulds
- Saprophytic: Found on decaying organic matter.
- Under suitable conditions, form plasmodium (multi-nucleated structure).
- In unfavorable conditions, plasmodium forms fruiting bodies bearing resistant spores.
- Spores: True wall, extremely durable, dispersed by air currents.
---
5. Protozoans *(All heterotrophs; live as predators or parasites)*
A) Amoeboid Protozoans
- Move & capture prey using pseudopodia (e.g., Amoeba).
- Marine forms have silica shells. Example: Entamoeba (parasite).
B) Flagellated Protozoans
- Free-living or parasitic; have flagella.
- Example: Trypanosoma (causes sleeping sickness).
C) Ciliated Protozoans
- Aquatic, actively moving with thousands of cilia.
- Gullet: Directs food into the cell. Example: Paramecium.
D) Sporozoans
- Infectious spore-like stage in their life cycle.
- Example: Plasmodium (causes malaria).

MOLECULAR GENETICS
NEET PYQS
Very important paragraph
Transcription
Second complexity of transcription
✓Primary transcripts contain both exon and introns and that are non -functional
✓So , we have to convert into functional we will do process called
SPLICING
✓In splicing, introns are removed and exon are joined in defined order
✓hnRNA undergoes additional processing called as capping and tailing
✓Capping
Nucleotide (methyl guanosine triphosphate) is added to the 5'-end of hnRNA
✓ Tailing
Adenylate residues (200-300) are added at 3'-end
✓Fully processed hnRNA = m RNA
✓Now this mature mRNA is transported into nucleus for translation
Give hearts ❤️❤️

1. Algae
Reproduction varies from vegetative (fragmentation) to asexual (spores) and sexual (gametes).
Used as a source of food (e.g., Spirulina), and in industries (agar extraction from red algae).
2. Bryophytes
Known for absorbing water through the entire surface, as they lack vascular tissue.
Often serve as pioneer species in soil formation and prevent soil erosion.
3. Pteridophytes
First plants to develop vascular tissue, allowing effective nutrient and water transport.
Commonly found in ornamental gardening (e.g., ferns) due to aesthetic appearance.
4. Gymnosperms
Includes economically important plants like pine and cedar, often used for timber and resins.
Seeds are often dispersed by wind due to their lightweight structure.
5. Angiosperms
Exhibit the greatest diversity among plants, dominating most terrestrial ecosystems.
Crucial for human life as they provide food, medicines, fibers, and other resources.
