Hey BYJU’S Achievers! In this exciting episode of the Mission Mid-Terms series, Ankita ma’am discusses important topics in your CBSE Class 9 Science Chapter 6, Tissues.

Some of the topics discussed in this class are as follows:
1. Definition of tissues
2. Cellular organization
3. Why do plants and animals have different types of tissues?

Tissue is a group of cells similar in structure and function. There are two types of plant tissues, meristematic and permanent. Meristematic tissue is the dividing tissue present in the growing regions of the plant, while the permanent tissues are derived from meristematic tissue once they lose the ability to divide. Meristematic tissues are classified as simple and complex tissues. Join this class to learn more about tissues.

Ma'am please don't talk to other students while you are teaching because we get distracted and loose our interest

🎯 Key Takeaways for quick navigation:

00:02: Anita *introduces the class on tissues and encourages focus; not her birthday today.*
01:54: Anita *emphasizes the importance of attention, welcoming subscribers to the educational channel.*
02:47: Anita *addresses the relevance of the session for Class 9 students and invites them to leave if it's not beneficial.*
05:28: Tissues *are groups of cells performing a specific function; divided into plant and animal tissues.*
06:51: Plant *tissues - Meristematic tissues divide actively, crucial for plant growth; categorized into apical, lateral, and intercalary meristems.*
09:29: Permanent *tissues differ from meristematic due to a lack of division, categorized into simple (parenchyma, collenchyma, sclerenchyma) and complex tissues (xylem, phloem).*
13:36: Parenchyma: *Characteristics - oval cells, intercellular spaces; subdivided into chlorenchyma (chloroplast-rich) and aerenchyma (air cavities).*
16:24: Collenchyma: *Notably thick-walled cells, providing flexibility, typically found in plant climbers.*
17:46: Sclerenchyma: *Features thick lignified cell walls, commonly in seed coatings and husks, offering mechanical support.*
21:19: Protective *tissues like leaf and root epidermis guard against water loss and invasion; cork cells possess suberin for impermeability.*
24:36: The *complex permanent tissues are xylem and phloem. Xylem transports water and minerals, Phloem moves food materials.*
25:18 Xylem *tissues transport water and minerals from roots to other plant parts in one direction only.*
26:10 Xylem *comprises dead cells, facilitating unidirectional movement from roots to plant tops.*
26:38 Phloem *transports food bidirectionally, both upwards and downwards.*
36:35 Skeletal *muscles are voluntary and enable body movements.*
38:54 Smooth *muscles are involuntary, found in organs like the esophagus and intestines.*
41:25 Cardiac *muscles are solely present in the heart, constantly active, and involuntary.*
43:11 Connective *tissues like loose connective tissue and adipose tissue provide support and insulation, respectively.*
47:43 Tendons *connect skeletal muscles to bones, ligaments join bone to bone.*
48:40 Blood *is a fluid connective tissue consisting of plasma, RBCs, WBCs, and platelets.*
49:47 Nervous *tissue, comprising neurons, transmits electrical impulses in the body.*
51:56 Lymph *is fluid from blood capillaries forming tissue fluid, without RBCs or platelets.*
52:42 Lymphatic *system forms tissue fluid, different from blood with fewer WBCs and plasma.*
53:10 Ligaments *join bone to bone, more elastic than tendons, facilitating movement.*
53:39 Cartilage *provides soft cushioning between bones, less rigid compared to ligaments.*

CAN YOU GIVE SOME MORE DIFFERENCES BETWEEN SIMPLE AND COMPLES MERISTEMATIC TISSUE

[aswathysaburaj]

Thnx a lot ma'am for this wonderful session
-Vaishnavi

[aaravrajshekar]

the explanation was very good but here were too many sponsorships

[kirthikjha]

Mam instead of unstriated muscular tissue we can also call it as smooth muscle

[aryansingh]

Thankyou so much for the session ❤❤❤❤

[ryanhajiyani]

It helped me at the last night of exam

[adeshwariach]

Thanks to all byjus team for great explanation of tissues

[RadheRadhe-ik]

Mam someone told me tissue is divided in two parts, simple tissue and complex tissue and simple tissue is known as meristematic tissue and permanent tissue is a type of complex tissue is it right or not, mam please tell me
, i am so confused.

[AnilKumar-mtgk]

Thank u mam for this wonderful and cheerful session ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

[fatimasiddiqui]

prosenchyma is also a type of parenchyma, is it not important for our syllabus

[Jai_shree_ram_]

Thanks ma'am for your great explanation. 🙂🙂🙂🙂🙂

[BlissfulBrush.]

Mam actually I have doubt Can you please say me about the Fibrous Basement membrane

[bushrahuda]

THANK YOU MA'AM FOR CLEAR EXPLANATION ❤

[sakshidubey]

Is unstriated muscle voluntary or involuntary????
Having a confusion
Getting different answers from different sources

[shifaahmad]

It helped me a lot!! Thanks a lot to the whole team of byju's..!

[UNKNOWNREAL]

Day after tomorrow is my Aakash FST, thank you maam so much for explaining it so quickly and steadily, than you maam appreciate it 🙇

[charusharma]

Permanent tissue can you tell me the defination
