Editor's Notes
- #2 WELCOME BACK to my channel Today if you new to channel please do subscribe the channel and hit the bell icon to get early notifications about upcoming videos. So lets start with solving some questions from previous concept then we will move to our todays topic
- #3 There are the question Simple and compound P T
- #4 THIS WAS THE experimental set up in last class we watched the full video of this experiment where we recognised meristematic tissues and then learnt about the types of meristematic tissues , apical intercalary and ,lateral meristem cells and their natures and characteristics .
- #5 Now see there is and dicot plant an apple tree See it is having 3 different parts leaf, fruit and stem all are having diffent functions as well as all are having different physical natures
- #6 So out todays topic is about permanent tissues .
- #7 Here we can divide PT in 2 types on the bases of no. of tissues composed of if single type of tissues it will be come under simple P T If it is composed of 2 or more then 2 types it will fall under compound P T Simple type are protective and supporting So in this video we will talk about only simple P T and we will discuss parenchyma and collenchyma only in detail .
- #8 Lets get started with the characteristics of permanent tissues
- #9 If you got the answer write it down in the comment box below
- #10 Lets start with parenchyma cells Word parenchyma comes from greak word para meaning beside and enchyma means in filling Making sense of in beside filling also these acts like ground cells also know as ground tissues
- #11 There is some of the diagrams showing parenchyma tissues indicating presence of intercellular spaces bw cells of parenchyma
- #12 There are some of the characteristics of the parenchyma cells These cells are living , shape will be rounded due to turgidity, these cells are isodiametric it means their diameter is same in all the directions , These cells are having thin cell wall enclosing dense cytoplasm with small nucleus and a large central vacuole for the performing storage function.
- #15 You might have observed this kind situation where wind blows and some of leaves deattaces from plants while some doesn’t deattaches at all. Do you think that they are having some glue like substances which helps them in staying attached. So yes there is tissues names collenchyma
- #16 Now see the origin of word is from greak word kola means glue ; enkhuma means infusion means glue infusion Here we can observe t. s section Showing
