I did Biology in my Waec 😄

Michael Chijindu · 23rd Jun 2026, 9:24 AM

And I know this one welll

Emmanuel Emmanuel · 23rd Jun 2026, 11:40 AM

Good to hear that

Michael Chijindu · 23rd Jun 2026, 1:16 PM

Thanks

Emmanuel Emmanuel · 23rd Jun 2026, 11:40 AM

Which year do you wrote waec

Michael Chijindu · 23rd Jun 2026, 1:16 PM

Last year

Emmanuel Emmanuel · 23rd Jun 2026, 1:19 PM

Okay

Michael Chijindu · 23rd Jun 2026, 5:53 PM

Yepp

Emmanuel Emmanuel · 23rd Jun 2026, 1:20 PM

I did my 5 year's ago

Michael Chijindu · 23rd Jun 2026, 5:53 PM

5? 🤔

Michael Chijindu · 23rd Jun 2026, 9:24 AM

The answer is B (Xylem)

Michael Chijindu · 23rd Jun 2026, 9:25 AM

Xylem is basically the plant's water pipe

Michael Chijindu · 23rd Jun 2026, 9:25 AM

It carries water and minerals from the roots aaaaall the way up to the leaves

Michael Chijindu · 23rd Jun 2026, 9:27 AM

Phloem does food(nutrients), not water.

Michael Chijindu · 23rd Jun 2026, 9:27 AM

The cortex and epidermis are just outer layers, they don't transport anything

Michael Chijindu · 23rd Jun 2026, 9:28 AM

Easy way to remember (For me tho): Xylem = X-tra water going up 😁

Emmanuel Emmanuel · 23rd Jun 2026, 11:41 AM

Okay

Michael Chijindu · 23rd Jun 2026, 1:16 PM

Thanks

Emmanuel Emmanuel · 23rd Jun 2026, 1:20 PM

Exactly 💯

Emmanuel Emmanuel · 23rd Jun 2026, 1:26 PM

Michael Chijindu · 23rd Jun 2026, 1:16 PM

Yh ✍🏾

Prosper Erharuyi · 23rd Jun 2026, 11:12 AM

The answer is B (Xylem)the part of the plant responsible for the conduction of water is the xylem , it helps in moving water and dissolved mineral salts from the roots to the other part of the plant

Emmanuel Emmanuel · 23rd Jun 2026, 11:41 AM

Wow 😲

Michael Chijindu · 23rd Jun 2026, 1:17 PM

Like what's going on

Emmanuel Emmanuel · 23rd Jun 2026, 1:20 PM

Nothing oo

Okay

Emmanuel Emmanuel · 23rd Jun 2026, 11:41 AM

The comment section is so engaging

Emmanuel Emmanuel · 23rd Jun 2026, 1:13 PM

We keep moving regardless

Michael Chijindu · 23rd Jun 2026, 1:18 PM

Absolutely

Emmanuel Emmanuel · 23rd Jun 2026, 1:21 PM

Perfect

Michael Chijindu · 23rd Jun 2026, 1:18 PM

Indeed

Emmanuel Emmanuel · 23rd Jun 2026, 1:20 PM

Yes of course

Emmanuel Emmanuel · 23rd Jun 2026, 1:21 PM

Yes ooo

Emmanuel Emmanuel · 23rd Jun 2026, 11:52 AM

The correct answer is B. Xylem.

Emmanuel Emmanuel · 23rd Jun 2026, 12:36 PM

I'm really sure

Michael Chijindu · 23rd Jun 2026, 1:19 PM

It is 😁

Emmanuel Emmanuel · 23rd Jun 2026, 1:21 PM

Exactly

Emmanuel Emmanuel · 23rd Jun 2026, 1:21 PM

Wow

Emmanuel Emmanuel · 23rd Jun 2026, 1:21 PM

Same here

Michael Chijindu · 23rd Jun 2026, 1:18 PM

Correct

Emmanuel Emmanuel · 23rd Jun 2026, 1:24 PM

Exactly 💯

Emmanuel Emmanuel · 23rd Jun 2026, 11:53 AM

Specialized Vessel Elements and Tracheids: Xylem consists of long, hollow tubes called vessels and tracheids. These cells are dead at maturity and have lost their internal contents, creating an open, continuous pipeline perfectly designed for water to flow through smoothly.

Emmanuel Emmanuel · 23rd Jun 2026, 1:13 PM

Perfect

Michael Chijindu · 23rd Jun 2026, 1:19 PM

Hmm 🤔 ✍🏾

Emmanuel Emmanuel · 23rd Jun 2026, 1:22 PM

What

Emmanuel Emmanuel · 23rd Jun 2026, 11:53 AM

Lignified Cell Walls: The walls of xylem cells are reinforced with a tough polymer called lignin. This makes the tubes incredibly strong and rigid, preventing them from collapsing under the immense negative pressure (suction) created as water is pulled up the plant.

Emmanuel Emmanuel · 23rd Jun 2026, 1:13 PM

I stated it well

Emmanuel Emmanuel · 23rd Jun 2026, 11:53 AM

Facilitates Transpiration Pull: Xylem forms an unbroken column of water from the roots all the way to the leaves. When water evaporates from the leaves (transpiration), it creates a strong pulling force that draws water upward through the xylem, similar to drinking through a straw

Emmanuel Emmanuel · 23rd Jun 2026, 1:14 PM

You all can go through this explanation

Emmanuel Emmanuel · 23rd Jun 2026, 11:53 AM

Capillary Action Support: The narrow diameter of xylem vessels, combined with the properties of water (cohesion between water molecules and adhesion to the cell walls), helps water climb upwards against the force of gravity.

Emmanuel Emmanuel · 23rd Jun 2026, 12:37 PM

Each nd everyone should learn 1 or 2 from this

Emmanuel Emmanuel · 23rd Jun 2026, 1:24 PM

Exactly

Emmanuel Emmanuel · 23rd Jun 2026, 11:53 AM

One-Way Transport System: Xylem is biologically structured for unidirectional (one-way) transport. It moves water and dissolved minerals exclusively upward from the roots to the stems and leaves, where it is needed for photosynthesis.

Emmanuel Emmanuel · 23rd Jun 2026, 1:14 PM

We move regardless

Emmanuel Emmanuel · 23rd Jun 2026, 11:54 AM

A. Phloem: Responsible for transporting food (sugars/carbohydrates) made during photosynthesis from the leaves to the rest of the plant.

Emmanuel Emmanuel · 23rd Jun 2026, 12:36 PM

This is the explanation for phloem

Emmanuel Emmanuel · 23rd Jun 2026, 11:54 AM

C. Cortex: A layer of tissue below the epidermis used primarily for food storage and transport of materials into the vascular core

Emmanuel Emmanuel · 23rd Jun 2026, 12:37 PM

Well stated

Emmanuel Emmanuel · 23rd Jun 2026, 11:54 AM

D. Epidermis: The outermost protective layer of the plant that prevents water loss and protects against injury.

Emmanuel Emmanuel · 23rd Jun 2026, 12:37 PM

Correct 💯

Jaiyeola Ayomide · 23rd Jun 2026, 12:33 PM

The answer is B .Xylem

Emmanuel Emmanuel · 23rd Jun 2026, 12:37 PM

Exactly 💯

Emmanuel Emmanuel · 23rd Jun 2026, 1:14 PM

You got it right

Emmanuel Emmanuel · 23rd Jun 2026, 1:16 PM

Or is their anyone who think xylem is not correct

Emmanuel Emmanuel · 23rd Jun 2026, 1:25 PM

Let me see if their is

Emmanuel Emmanuel · 23rd Jun 2026, 1:16 PM
