*Angiosperms vs Gymnosperms - "Phal wale vs Nange Beej wale Pode"*
Both are *seed plants* = Spermatophytes. Means they make seeds instead of
spores like ferns. But seed ka style alag hai.
*1. Basic Definition*
**Type** **Meaning** **Urdu** **Example**
**Angiosperms** “Angio” = covered, “Sperm” = seed ****ڈﮬﮑﮯ ﺑﯿﺞ واﻟﮯ ﭘﻮدے
Mango, Wheat, Rose, Grass
**Gymnosperms** “Gymno” = naked, “Sperm” = seed ****ﻧﻨﮕﮯ ﺑﯿﺞ واﻟﮯ ﭘﻮدے
Pine, Deodar, Cycas, Ginkgo
*2. 8 Main Differences - Exam ke liye best*
**Feature** **Gymnosperms** **Angiosperms**
**1. Seeds** **Naked** - Seeds sit openly on cone scales. No fruit/ovary
**Covered** - Seeds inside fruit/ovary. Fruit = mature ovary
**2. Flowers** No true flowers. Only cones - male + female cones separate
True flowers with petals, sepals, stamen, carpel. Colorful to attract insects
**3. Fruit** No fruit formed. Seed + cone scale only Fruit always forms.
Mango, apple, pea pod = all fruits
**4. Leaves** Needle-like, thick, waxy. Evergreen. Less water loss Broad, thin,
flat. Many shed in autumn = deciduous
**5. Pollination** Mostly by **wind** = anemophily. Pollen is light, in huge
amount By **insects, birds, wind, water**. Flowers have nectar + smell for
insects
**6. Fertilization** Takes more time. No double fertilization **Double
fertilization** happens → 1 seed + 1 endosperm for food
**7. Vessels** Xylem has only tracheids. No vessels. Water moves slowly
Xylem has tracheids + vessels. Fast water transport
**8. Evolution + Age** Older, 300 million years. “Living fossils” Newer, 140 million
years. 80% of all plants today
**9. Habitat** Cold, dry areas. Mountains, Taiga forests Everywhere - deserts,
oceans, mountains, plains
**10. Examples PK** Deodar, Kail, Fir, Chir pine in KPK/GB Wheat, rice,
cotton, mango, rose all over Pakistan
*3. Reproduction - How they make babies*
*Gymnosperms - Simple 3 steps*:
1. Male cone → makes pollen. Wind blows pollen to female cone
2. Pollen grain grows tube, sperm goes to egg inside ovule
3. Egg becomes seed on cone scale. Cone opens, seed falls → new plant
*Angiosperms - 4 steps + Double fertilization*:
1. Flower → pollen goes to stigma of same/other flower
2. Pollen tube grows down to ovule inside ovary
3. *Double fertilization*: 1 sperm + egg = zygote → embryo/seed. 2nd sperm + 2
Both are *seed plants* = Spermatophytes. Means they make seeds instead of
spores like ferns. But seed ka style alag hai.
