TWo main methods for Asexual Reproduction
Tubers, Suckers
what is sexual reproduction in plants
sexual reproduction in plants is carried out by using seeds
what is pollination
pollination is the transfer of pollen from the anthlerr to the stigma
what is fertilization
fertilization is the fusion of an male and female sex cells (gametes) to form an zygate which later develops in the embryo
What is plant anatony
its deals with the structure of the plant
what is plant physiology
study of the functions of the structure (root stem and leafs)
what is soil
soil is an loose surface material that covers most lands and it consists of inorganic and organic matter
what are the physical properties of soil
Texture,Structure, colour and drainage
what is micro nuterients
its quanity of small amount of essential nutrients deprived from the soil
what is macro nutrients
its an quantanity of large amount of essential nuterients deprived from the soil
what does macro nutrients use
nitrogen,phorusphus and potassium
what does micro nutrients use
calicum, magnesium and sulfur
what is cropping system
it is the arrangement of proudcing crops or an range of crops
what is mono culture
mono culture is the cultivation of one crop on an arc of land for many year
3 advantages of mono culture
large quantities of crops can be reproduced, having specalization in reproducing the crop and encourages mechanization
3 disadvantages of mono culture
it can lead to soil exhaustation, pest and dieases population increases and its risky
what is agriculture
it is the cultivation of growing crops and the rearing of animals and using scientific knowledge
what is Non coventional Farming system
it is methodologies which use different approaches, from hydroponics to vertical agriculture and urban farming, agroecology, permaculture, and organic production, among others.
examples of suckers
bananas,pinapples
examples of tubers

Tomato
functions of the root
it anchors the plant and gets the absorbation of water and nutrients
functions of the stem
the stem provides support for the plant and stem can act as storage organs as well
functions of the cambium
it is responsible for secondary growth
functions of pholem
it transport food/ glucose
functions of xylem
it transport water and minerals from the root to other parts of the plants
functions of the vascular bundle
the vascular bundle is the transport system in the plants
what is the flower
it is the main organ of sexual reproduction
what are the types of weathering
physical weathering
biological weathering
chemical weathering
what is soil formation affected by
climate,slope flora and fauna
what is organic matter
it is the dead or decomposed plant and animal mattter in the soil
how important is organic matter
it adds nutreints in the soil and provides energy for the soil organism
what does the soil colors represent
red- well drained and minerals
black-rich in organic matter
brown- rich in nutrients and organic matter
grey- water logged and acidic
what is self pollination
self pollination can be transfered from the antler to the stigma of the same flower or to another flower on the same time
examples of rhizome
ginger and saffori
if the leave is getting yellowish what must u use
nitrogen if it is being prevented
calcium if its not receiving any motso muen
also magnesium
types of soil
